Diffuse reflection laser ranging and high resolution imaging synchronous measurement photoelectric telescope system

Abstract

The invention relates to a diffuse reflection laser ranging and high-resolution imaging synchronous measurement photoelectric telescope system capable of being used for space debris and belongs to the technical field of photoelectric telescopes. The system comprises a laser emitting part, an echo receiving part and a self-adaptive optical imaging part. According to the laser emitting part, laser light emitted by a laser enters a telescope through a laser emitting light path to be emitted to a space target. According to the echo receiving part, an echo light beam is received by the telescope and then enters an echo receiving and detecting light path, echo signals are generated and then transmitted to a laser ranging control circuit, and a laser ranging distance value is obtained after software processing. According to the self-adaptive optical imaging part, the space target light is received by the telescope, enters a self-adaptive optical system and is shrunk by a beam shrinking light path, a Hartmann sensor and a wavefront detector are used for detecting overall wavefront inclination and wavefront errors to obtain the overall wavefront inclination degree and wavefront error data which are used for controlling a fine tracking system to correct the wavefront inclination and controlling a deformable mirror to correct the wavefront errors, and therefore a high-resolution image is obtained.

Description

technical field [0001] The invention belongs to the technical field of photoelectric telescopes, and relates to a photoelectric telescope system and a photoelectric telescope, in particular, it can be used for simultaneous measurement of space debris diffuse reflection laser ranging and high-resolution imaging. Background technique [0002] Satellite Laser Ranging (SLR) is a technology initiated by NASA in the early 1960s to use space technology to study geodynamics, geodesy, geophysics and astronomy, etc. means. It uses the measurement of the round-trip flight time of laser pulses between the observation station and the satellite, thereby calculating the distance from the satellite to the station. It is currently the most accurate technical method in space target distance measurement. Since the laser is monochromatic and has good directionality, the laser ranging can simultaneously provide the target's azimuth, height and distance information. Conventional laser ranging r...
