Abstract

The invention discloses a light curtain target simulation verification system, which comprises a main control box module, a parallel light curtain module, a photoelectric receiving module and a waveform display module. The main control box module is connected with the parallel light curtain module to control the parallel light curtain The on-off of the module, the parallel light curtain module generates a parallel light curtain and irradiates the photoelectric receiving module, and the waveform display module is connected with the parallel light curtain module and the photoelectric receiving module respectively, and is used to collect and display the data of the parallel light curtain module and the photoelectric receiving module. transient waveform. The invention utilizes the main control box module to control the on-off of the parallel light curtain to realize the simulation of the moment when the warhead fragments pass through the light curtain, so that the experiment can be carried out indoors, which saves manpower and financial resources and is not dangerous; The method of averaging the test results of the light curtain further reduces the systematic error.

Description

technical field [0001] The invention belongs to the technical field of optical testing, in particular to a light curtain target simulation calibration system. Background technique [0002] With the development of optical testing technology, its application in all walks of life is becoming more and more extensive, such as testing parameters such as speed, direction, and flight coordinates during the flight of warhead fragments. [0003] An article titled "Light Curtain Target Test Technology for Measurement of Small Fragment Groups" published in the Journal of High Pressure Physics discloses a light curtain target. The receiving module of photoelectric conversion, when the warhead fragments pass through the light curtain, the receiving module will undergo photoelectric conversion due to the warhead fragments covering the irradiated parallel light, and feel the warhead fragments passing through the moment, and the time difference between the fixed light curtains will be compar...
