AIR POLLUTION TESTING COMPLEX Russian patent published in 1994 - IPC

FIELD: remote probing of gaseous components. SUBSTANCE: optical testing system has differential absorption lidar and unit for multicomponent water analyzing. Differential absorption lidar has the following members mounted along the path of reflected radiation: guiding system, optical receiving aerial, optical-mechanical unit and system for receiving and treating signal. Output of tunable laser irradiator is connected optically with input of guiding system and with input of calibration unit simultaneously through optical commutator. Output of calibration unit is connected with the second input of mechanical-optical unit. Output of guiding system is connected with input of TV viewfinder through rotating mirror. Inputs-outputs of computational-control complex are connected with corresponding inputs-outputs of TV viewfinder, optical-mechanical unit, guiding system, tunable laser irradiator, target indication transmission system, plotting device and time frequency synchronization system through communication trunk. In the device for multicomponent analyzing of air, the guiding system, optical receiving aerial, spectrum analyzer and photodetecting device are placed in series along the path of radiation received. Output of laser irradiator is optically communicated with input of guiding system and with input of calibration unit through optical commutator simultaneously. Output of calibration unit is connected with input of spectrum analyzer. Output of guiding system is connected with input of TV viewfinder through rotatable mirror. Inputs-outputs of coordinate indication system, target indication reception system, TV viewfinder, guiding system, laser irradiator, photodetecting unit and time frequency synchronization system are connected with corresponding inputs-outputs of computation-control complex. Target indication transmission system of differential absorption lidar is connected with system for reception of target indications of the device through communication channel for carrying multicomponent analyze out. EFFECT: improved precision. 3 cl, 2 dwg
