| description | The invention belongs to the technical field of artillery projectile initial-speed measurement and specifically relates to a reflection-type laser curtain speed measurement device. To solve the technical problem, the speed measurement device includes a first laser curtain system, a second laser curtain system and a signal processor. Each laser curtain system includes a fan-shaped laser device, an imaging lens, an optical slit, a narrow-band optical filter and a photoelectric detector. The reflection-type laser curtain speed measurement device calibrates an artillery fire initial speed and is provided with laser curtain structures, which are spaced in a preset distance, and relies on reflection light generated when a projectile passes. Photoelectric detectors convert light signals with time difference into electrical signals. A signal processor analyzes the electrical signals and according to the preset distance, an average speed of the projectile when passing two fan-surface light sources is calculated. The s |
