Being kernel part of whole system, the computer is in use for sending out control commands to control RF drive frequency applied to AOTF so as to change wavelength, and obtain image of object in the wavelength. Also, the computer is in use for controlling value of voltage applied to LCVR so as to change linear phase delay LCVR. Moreover, the computer collects image information of object to be measured, and carries out process for the collected images.

Features are: good adaptability, and raised detection capability.

Description

technical field [0001] The invention relates to a hyperspectral full-polarization three-dimensional imaging integrated detection system for space-borne, airborne and ground-to-ground remote sensing and deep space detection. Background technique [0002] Optical remote sensing is essentially a process in which light waves interact with measured ground objects, thereby affecting the parameters of light waves (amplitude, frequency, phase, polarization), and achieving the process of detecting and identifying targets. The remote sensing system is a complex system involving physics, mathematics, atmosphere, geology, oceanography, etc. The physical laws it follows are essentially different from traditional physics. In-depth research on remote sensing mechanisms is the key to improving the application level of remote sensing. However, in terms of remote sensing applications, the contradiction between data explosion and information hunger is still very significant. According to NASA ...
