Abstract

The invention discloses a light screen device with sending and receiving functions and a test method of the light screen. A light source and a receiving light device are installed on a circuit board to form a detection device main body with sending and receiving functions, and the light is reflected by an illuminator to form a detection screen. The detection device and the reflecting device are both provided with angle regulatory mechanisms with the same structure, the angle regulatory mechanism can adjust the angle of an incidence screen and a reflecting screen to ensure the angle between two screens by cooperating with the light screen. The main light axis of the light-emitting device is ensured to be at the same plane with the main light axis of the receiving device. The light screen device has the advantages of simple structure, fewer links, small cumulative error, high measurement precision, and convenient assembling; the light screen device not only can be used for measuring the speed of a pellet, but also used for carrying out the denseness degree test and the measurement of pellet flying angle and direction; and the light screen device broadens the measurement scope of the pellet.

Description

technical field

[0001] The invention belongs to the technical field of shooting range testing, and mainly relates to a light curtain target and a test method for measuring the velocity and density of flying projectiles of various calibers, in particular to a light curtain target device integrating a light source and a receiving device. Specifically, it relates to a light curtain target device and a light curtain target testing method combining sending and receiving. Background technique

[0002] In the production and development of gun shells and propellants, the initial velocity of the projectile is a must-test parameter. Using four light curtain targets to form a certain formation can test the target density of the projectile. If six light curtain targets are used to form a certain In addition to the velocity density, the formation can also test the velocity vector of the projectile. In a test system with four light curtains or six light curtains, the geometric angle meas...
