Abstract

The invention relates to the technical field of photoelectric testing, in particular to a splicable collimation-like light curtain light source device and a splicing method thereof. The invention aims to solve the problems of how to form a large-size safety light curtain and poor light source collimation in detection. According to the technical scheme, the device comprises a Powell prism support, a Powell prism, a point laser, a Fresnel lens, an upper clamping plate, a lower clamping plate and a diaphragm. The diaphragm piece is arranged between the upper clamping plate and the lower clamping plate and can move left and right along the lower clamping plate, the Fresnel lens and the Powell prism are arranged on the front side and the rear side of the diaphragm piece respectively, the focus of the Fresnel lens coincides with the focus of the Powell prism, and the point laser is arranged at the front end of the Powell prism. And emergent light coincides with the optical axis of the Powell prism, and the Fresnel lens, the point laser and the Powell prism are connected into a whole through the lower clamping plate and the upper clamping plate.

Description

technical field [0001] The invention relates to the technical field of photoelectric testing, in particular to a splicable collimated light curtain light source device and a splicing method thereof. Background technique [0002] In the damage performance evaluation of weapon system, the projectile's flight speed and target coordinate parameters are two important indexes. The current research on projectile velocity testing is mainly non-contact testing, such as: light curtain target. [0003] As a widely used weapon and a common section measuring instrument on industrial shooting ranges, light curtain target consists of LED array light source, photodiode array, signal processing circuit and supporting components. It has the characteristics of high test accuracy, flexible customization of test target surface, low requirements for test environment, and repeatable test. Therefore, light curtain targets are widely used in indoor shooting ranges. Since the light curtain target i...
