Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:
[0023] The multi-spectral earth observation laser radar system provided by the present invention specifically adopts the following technical solutions.
[0024] see figure 1 , including semiconductor and solid-state laser transmitter 1, laser scanner 2, laser rangefinder 3, optical receiver 4, laser scanning controller 5, rangefinder controller 6, signal processing circuit and computer 7; semiconductor and solid-state laser The laser light emitted by 1 reaches the detection object after passing through the laser scanner 2. At the same time, the laser light emitted by the laser rangefinder 3 also reaches the detection object. The wave signal is captured by the optical receiver 4, and the signal captured by the optical receiver 4 and the distance information obtained by the laser range finder 3 are sent to the signal processing circuit and the compu...
