Laser radar transmission type coaxial transmitting and receiving equipment

Abstract

The present invention discloses a laser radar transmission-type coaxial transmitting and receiving device. (a) The transmission light path is provided with a laser (1), a concave lens (4), a reflecting mirror (5) which is provided with an angle of 40-50 DEG to the light path, and an aspherical mirror (6) which are provided in sequence. (b) A phototube (12) which has an output end electrically connected with the synchronous triggering input port (141) of the photon counter (14) is provided at the position near the concave lens (4). (c) The receiving light path is provided with the aspherical mirror (6) and the reflecting mirror (5) in sequence. The reflecting light path of the reflecting mirror (5) is provided with a reflecting mirror (7), a diaphragm (8), a focusing lens (9), a color filter (10), a focusing lens (1) and a photoelectric detector (13) which are connected in sequence. The output end of the photoelectric detector (13) is electrically connected with the input port (142) of the photon counter (14). The device of the invention has the advantages of simple structure, easy installation and debugging, low cost, stable and reliable work and convenient maintenance. The device can be widely applied in the laser radar.

AI Technical Summary

Benefits of technology

This patented technology describes various technical improvements over existing technologies like LC'S or CWL systems. These new techniques aim to improve upon these traditional methods while maintain their benefits. They include improved efficiency, reduced size, simplified construction process, elimination of multiple sources of noise, increased sensitivity, higher precision measurements, longer life span without requiring repairs, lower costs compared to current alternatives, and more precise alignment than previous ones. Additionally, they provide means to detect reflected lights caused by ambient air particles instead of relying solely on the presence of any materials themselves. Overall, these innovations enhances the performance and functionality of the overall equipment.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the accuracy and reliability of measuring atmospheratic environmental parameters like altitude, wind speed, humidity levels, particle size distributions, turbulence intensity, etc., without compromising their integrity due to variations caused by factors other than constant pressure. Existing methods involve multiple components which require precise alignment during installation, resulting in instabilities when subjected to vibration forces. Additionally, current solutions either lack sufficient precision or rely heavily relying upon temperatures controlled within specific ranges, causing unstable measurements over time.
