specific Embodiment approach 1
[0007] Embodiment 1: Combining figure 1 Illustrate this specific embodiment, exponential gain modulation distance imager, it is by pulsed laser 1, the first light splitter 2, launch optical shaping system 3, high-voltage DC power supply 5, delay generator 6, photodetector 7, control processor 8. Composed of a high-voltage modulation power supply 9, a gate power supply 10, a first ICCD imager 11, a second ICCD imager 4, a second beam splitter 12 and a receiving optical system 13, the beam output by the pulse laser 1 passes through the first beam splitter 2 Divided into the first reflected light and the first transmitted light, the first reflected light is incident on the light-sensing end of the photodetector 7, the first transmitted light is incident on the input end of the emission optical shaping system 3, and is emitted by the emission optical shaping system 3 The end transmits to the receiving end of the receiving optical system 13, and the output end of the receiving opti...
specific Embodiment approach 2
[0009] Embodiment 2: The difference between this embodiment and the exponential gain modulation range imager described in Embodiment 1 is that the pulsed laser 1 has a power of 1KW-100MW, a line width of 0.01nm-10nm, and a pulse width of 1ns-1000ns of pulsed lasers.
specific Embodiment approach 3
[0010] Embodiment 3: The difference between this embodiment and the exponential gain modulation range imager described in Embodiment 1 or Embodiment 2 is that the voltage range of the high-voltage DC power supply 5 is 500V-1100V.
