The research and development of laser destiny originated from the end of the 1960s of the previous century. It was first used in the military field. Since its commercialization was officially implemented in 1995, it has developed more and more influences in the fields of testing and resource surveying. In the development of “black technology” that is more and more unmanned. Liddy is one of the focus technologies in the development of “black technology” that is popular in the industry. With the development and perfection of technology, the application scope of laser detachment is becoming increasingly wider. The environmental monitoring field is a very important aspect, which can be used to measure changes in particulate matter, ozone, temperature and humidity, etc.
The Anhui Optical Secure Machinery Research Institute of Chinese Academy of Sciences established the largest L625 laser detonation system in my country at that time, which was used to detect the distribution of advective layer gas solvent. The laser detonation system was selected by the American National Navigation Administration as one of the 10 laser detonation stations in the world. Later, Sugar baby has developed ultraviolet differential receiving laser determinant that detects advection ozone, movable double-wavelength meter scattering L300 laser determinant, car-type Raman-meter scattering laser determinant, etc., and is this dream true or false, and is it regarded as a stone for the knowledge competition? Wide attention. Sugar daddy
Recently, the instrument information network editor specialized in the application of laser lightda in the field of environmental monitoring. Academician Liu Wenqing, director of the Anhui Optical Secret Machinery Research Institute of Chinese Academy of Sciences. Academician Liu introduced the application, technical development and future technical needs of LiDAR in our environmental monitoring field in detail.
Instrument: We know that Academician Liu has many research results in the environmental light tags: entertainment circle, strong women, female supporting roles, and time travel fields. Tomorrow we will focus on air quality monitoring, which has many types of air quality monitoring instruments and technologies, such as the regular six parameters, VOCs monitoring instruments, laser lightning, satellite remoteness, etc. First, please ask Academician Liu to discuss with us todayWhat is the overall situation of the air quality monitoring device? What are the differences between domestic environmental monitoring devices and imported products of the same type? Liu Wenqing: In the current stage of my country’s major environmental monitoring technology, it is still mainly focused on point-based monitoring methods, such as AQI six parameters, VOCs, etc. These monitoring equipment formed the current stage air air quality monitoring network in our country, making great contributions to our country’s air quality monitoring, and gradually formed environmental monitoring technical specifications, environmental monitoring analysis methods, and environmental quality standards systems with Chinese characteristics. The standard method adopted today is important to focus on human health. It measures the air quality within the scope of people’s daily career and mission activities. It can accurately monitor the content of air dissolved and purified gas in the air, but its limitation is important to obtain some purified compound concentration change information in the low-level and smaller regions, and lack data evolution information for indicators such as regional change of purified compound, time and space evolution. In recent years, with the rapid development of analyzers, combined with the satellite aerospace sense, the sounding sphere and tower can measure the vertical distribution characteristics of some gas solvents and gas components. However, the satellite aerospace sense directly obtains the entire layer of large air purification, which in turn will inevitably lead to errors in near-air purification. The sounding sphere and aircraft are affected by time and space, and this type of sounding equipment still lacks.
For regional revision and purification monitoring, quick and useful technical skills are required to conduct monitoring time and space within the regional scope. Compared with the above traditional point monitoring methods, the development of optical remote monitoring technologies such as laser point-to-line and then surface-based evolution methods have been changed, providing a new technical skill for the research and development of large-scale environments, fighting against many limitations in traditional large-scale environments, realizing large-scale remote detection of large-scale space, long-term, and multiple parameters. This type of technology has reached the international advanced level, especially the introduction of the phrase: We are married first and fall in love later, warm and cool. In terms of business application, we have conducted in-depth research and development based on the current needs of China’s environmental monitoring stage. This is something that foreign imported equipment cannot achieve. Today, domestic environmental monitoring instruments have basically broken the international failure position of imported products and have fully realized the Chinese manufacturing.
Instrument:Instrument:Sugar babyparticleEscortLaida technology is being received by more and more users. Please ask Academician Liu to discuss the particulate laser.ippines-sugar.net/”>Pinay escortRadar technology. What is the focus technology of particulate lidar? What is the application situation in the field of large-scale air environment in my country? The unique effect of this technology in air quality monitoring systems? Liu Wenqing: Lidar is mainly composed of lasers, transmitting and receiving optical systems, detectors, high-speed data acquisition cards and data analysis software. It is Sugar babyfocus technology lies in a stable and reliable laser device and an inversion algorithm with excellent functions. The laser single-pulse energy detail directly determines the detection height of the laser. Protecting the laser single-pulse energy can effectively guarantee the system signal-to-noise ratio and realize the detection of fantasy height. The laser single-pulse energy of different manufacturers at home and abroadPinay There are certain differences in the escort algorithm. The most widely used method is the Fernald method, which is also the inversion algorithm chosen by An Guang. When applying this algorithm, the choice of reference points is especially important. Generally, it is assumed that a clean and large-scale gas layer location that almost does not contain large gas solvent is used as a reference point to ensure the usefulness of the inversion result.
With the development of serious governance needs of “demonstrate environmental quality and improve environmental quality” and the transformation of governance mechanisms such as monitoring and acquisition, the local authorities can support the increasingly urgent request, especially quickly clear the gas quality. Monitoring point data changes, repurposing, changing emergency monitoring and rapid evaluation, etc. For regional enhancing problems and urgent needs for monitoring and governance, as a mature active and remote sensing technique, particulate laser light has the main meaning in the monitoring of large environments. Its application in environmental monitoring can be divided into the following points: 1) Vertical Monitoring: Monitor the changes in the border layer, clarify the sources of purification and trends; 2) Scanning monitoring of degree: The spatial three-dimensional distribution, variation rules and emission characteristics of regional purifiers can be obtained, and the contribution of local purifiers to the purification structure are understood; 3) Car loading and movement monitoring: conduct rapid traceability of purifiers, and follow up on purified emergencies; Sugar daddy4) Raider Group Network Monitor: It says that the clean-up cross-border transmission is provided for short-term air quality warning and pre-reported data support.
InstSugar daddyrument: Anhui Institute of Optical Machinery can be said to be a pioneer in the field of laser detection and research in my country. In the research and development of laser leida technology, what important tasks did Academician Liu do? What other tasks do you think will be in the future? daddyTechnical demand has been broken?
Liu Wenqing: Liddy can be divided into meter scattered laser lightda according to monitoring methods and monitoring types. Manila, large gas composition differential reception lidder, Raman lidder, etc. Our local particulate lidder and large gas differential reception lidder have achieved phased progress. We have submitted orders in the joint environment air guarantee missions of Beijing Olympic Games, Shanghai World Expo, Guangzhou Asia Games, Beijing APEC Conference, Beijing Jiusan Military Conference, Nanjing Youth Olympic Games, Fuzhou Youth Games, Zhengzhou SCO Shouzhuang Conference, and Uzhen Pharmaceutical Network. The satisfactory answer sheet also proves that our lidra has achieved certain results in stability and usefulness. However, there is still a certain lack in some aspects, and we need to make a step forward to perfection, such as: 1) Raman laser. Due to the limitations of its monitoring principles, Raman laser
