Embodiment Construction
[0023] The implementation examples of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] The main devices adopted in the present invention are described as follows:
[0025] 1) Collimator 2: The off-axis reflective collimator adopts ordinary processing, the telescope aperture is 350mm, the telescope focal length is 2m, and the parabolic surface requires RMS better than 1 / 20λ@632.8nm.
[0026] 2) Laser energy controllable attenuation device 3: Thorlabs company model NDC-25C-4, attenuation efficiency from 0 to (-40)db, diameter Φ25mm
[0027] 3) Delayed echo generator component 4: This device is a self-made device, mainly composed of a high-speed detector 4-1, a delayed echo generator 4-2 and a controllable fiber output laser 4-3, and a high-speed detector 4-1 After detecting the pulse signal, use the delayed echo generator 4-2 to generate a certain time-delayed analog echo signal, thereby triggering the...
