Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] The present invention is made up of pulse laser driving emission circuit, optical polarizer, optical analyzer, photodetector, signal processing circuit and computer system (see figure 1 ),in
[0023] Pulse laser drives the transmitting circuit and optical polarizer (semiconductor laser source and polarization optical system): the laser wavelength of the semiconductor laser belongs to the visible light range, and has a small divergence angle, which is suitable for cloudy or evening, night and other weather conditions. . The adoption of pulsed laser-driven transmitter circuit can eliminate external interference. Using an optical polarizer, the semiconductor laser is converted into linearly polarized light to improve the polarization sensitivity.
[0024] Optical analyzer and photodetector: use the optical analyzer to analyze the laser ...
