Abstract

The invention discloses a laser velocimeter comprising two support frames. A laser emitting device and a laser receiving device are fixedly installed on the tops of the two support frames that are arranged at the two sides of a road. The laser emitting device includes an emitter housing; two first mounting holes are formed in the emitter housing; an emitter outer cover is fixedly installed on thefirst mounting holes; and a laser emitter head is arranged in the emitter outer cover. A plurality of first indication lamps are fixedly arranged at the top of the emitter housing. According to the invention, the laser emitting device and the laser receiving device are installed at the two sides of the road or in the detection testing room to detect vehicle speeds. The laser velocimeter has advantages of small size, reduced weight, great convenience in installation, accurate beam, stable performance, and high precision is professionally suitable for fields of automobile safety crash testing, vehicle road traffic or other related precision speed measurement. During the detection process, the laser velocimeter is suitable for various terrains and has high adaptability to the terrain and highpracticability.

Description

technical field [0001] The invention relates to the field of laser speed measurement, in particular to a laser speed measurement instrument. Background technique [0002] The optical Doppler effect is one of the subject branches with broad application prospects in the field of optics, especially the research on the laser Doppler effect has great application potential. Internationally, the research work on the laser Doppler effect It was carried out earlier. Since the appearance of laser, foreign scholars have successively proposed and engaged in research work in this field, and have made certain progress in theory. Due to the complexity, stability, cost and life of the hand laser system, this The practicability of a research project is hindered. With the emergence and industrialization of semiconductor lasers, infinite vitality has been injected into the practical application of this research field. The laser Doppler velocimeter uses laser as the light source by hand, and ha...
