Abstract


For the problem of laser atmospheric attenuation characteristics , as well as compensation for laser power laser technology is widely used in laser rangefinder , laser radar, laser remote sensing technology in the field of the main problems encountered . This paper presents ' controllable constant laser power transmission research ', is based on the attenuation characteristics of atmospheric transmission of laser power , laser power through the initial launch with continuous modulation of the laser transmission distance variation constant power transmission. In the atmospheric transmission attenuation characteristics of the laser on the basis of in-depth analysis , considering the atmospheric attenuation factors , the establishment of laser atmospheric transmission attenuation expressions. Discrete control were established initial laser power , the initial laser power continuously changing control , change with distance constant power transmission expression, and the laser level , oblique way , when a vertical transfer simulation , to obtain the laser power constant transmission results . In order to achieve a constant laser power delivery , studied the primary laser power and continuously variable transmission distance between said given type, obtained by simulation curves . And the laser power to meet the required basis for the principle of non-linear modulation studies, has been simulated curve .
