Description

technical field [0001] The invention relates to a detection device for detecting projectile parameters and a corresponding detection method. Specifically, the invention relates to a controllable infrared photoelectric detection target device and a corresponding detection method. Background technique [0002] In the field of shooting range testing, the velocity of the projectile and the measurement of the coordinates of the target stand have always been the core test parameters for the development of guns, cannons, bullets, etc., which restrict the development of weapons and ammunition. The test equipment includes coil target, sky curtain target, light curtain target, laser target, etc. The sky curtain target is widely used in the shooting range due to its small size, light weight, simple operation and reliable performance. However, since the sky curtain target uses a visible light detector as The detection principle of the core unit is greatly affected by the natural environ...

Problems solved by technology

In order to improve the performance of the light curtain target, the patent CN101943549A proposed the design principle of using a line light source and a reflector to form a frame-type all-weather detection and speed measurement system. This method improves the sensitivity of the light curtain target, but due to the structure Limitation, the target surface is not large, and the reflective surface of the reflector is very flat. If there is a difference in the reflective material of the reflector, the reflected light will not easily fall on the photosensitive surface of the receiver.

In the patent CN202649229U, a laser reflection type large surface velocity measurement light curtain target was invented and designed. This light curtain target uses three optical lenses to splice the field of view and a 7-type array light source to form a detection light curtain, which is relatively expensive. Due to the large structure of the light source, the number of luminous tubes in the array is large, and the power consumption is as high as thousands of watts. In the continuous power supply system, the performance of some luminous tubes is different due to the jitter of the power supply during use, resulting in false triggering and stability. relatively poor
