Problems solved by technology

Due to the high cost and time-consuming of the field test, it is easy to be limited by the simulation conditions such as weather conditions, and a test equipment in the laboratory is needed to test and evaluate the performance of the laser altimeter
The laser altimetry system in the high-precision surveying and mapping camera system is used to measure the surface morphology. The peak output laser power is as high as megawatts, and the height measurement range is wide. The calibration methods and instruments of general laser altimeters cannot achieve accurate calibration. and performance testing

Abstract

The present invention discloses a laser ceilometer integrated test system and an integrated test method thereof, belonging to the technical field of lasers. The laser ceilometer integrated test systemand the integrated test method thereof achieve simulation of different surface features and simulation of a solar spectrum required by performance test of a laser-measured height subsystem in a mapping camera, and are applied to calibration of index parameters of the laser-measured height subsystem, wherein the index parameters comprise delay time constant of a whole machine, distance measurementprecision, a distance measurement range, distance measurement resolution, detection sensitivity, the maximum ranging, etc. The laser ceilometer integrated test system is high in integration, convenient and rapid in control, and can improve the reliability and the stability of the laser ceilometer integrated test system on the basis of achieving the functions mentioned above.

Description

technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to a laser altimeter comprehensive testing system and a comprehensive testing method thereof. Background technique [0002] Laser altimeter, essentially a large-range laser rangefinder, is a height measuring instrument that uses the characteristics of high directivity, high brightness, and high interference of laser beams to measure the height of objects. It has the advantages of long range, good directionality, strong anti-interference ability, and high measurement accuracy. The laser altimeter emits a laser beam to the target, and the photodetector receives the returned optical signal, and then obtains the height of the target to be measured through the relevant algorithm of laser height measurement. [0003] The laser altimeter comprehensive test system is used for testing and evaluating the performance of the laser altimeter system in the high-precision surveying and...
