Cirrus cloud detector based on image variable field of view

Abstract

The invention relates to a cirrus cloud detector based on an image variable field of view. The cirrus cloud detector comprises an upper industrial personal computer, a lower computer control system, amotor driving system, a temperature control system and a CCD imaging acquisition system. The upper industrial personal computer is in two-way communication connection with the lower computer controlsystem. The lower computer control system is in two-way communication connection with the temperature control system. The output end of the lower computer control system is connected with the input end of the motor driving system. The motor driving system is used for driving the CCD imaging acquisition system to rotate, and the temperature control system is used for providing a set temperature environment for the CCD imaging acquisition system. The motor driving system comprises a horizontal pitching stepping motor and an optical filter rotating disc motor. The output end of the lower computercontrol system is connected with the control input end of the horizontal pitching stepping motor and the control input end of the optical filter rotating disc motor. The horizontal pitching steppingmotor is used for driving the CCD imaging acquisition system to rotate. The optical path design is simple, and the detection time is short. Meanwhile, the detection precision of the cirrus cloud is improved.

Description

technical field [0001] The invention belongs to the field of atmospheric measuring instruments and equipment, and in particular relates to a cirrus cloud detector based on image variable field of view. Background technique [0002] Aerosol particles and clouds have important effects on atmospheric radiative transfer, optoelectronic engineering applications, weather and climate change. In particular, cirrus clouds are also a strong interference source of background radiation, which has strong forward scattering and reflects sunlight, and plays an important role in space target recognition and satellite ground remote sensing observation. The cirrus cloud layer is relatively high, thin and has good light transmission, so it is difficult to detect. Cirrus clouds can also interfere with ground-based instruments to measure the properties of aerosol particles, and the microphysical and optical characteristics of cirrus clouds have always been a hot topic in international research. ...
