Because of the laser coherence, resulting in remote sensing system and laser difference frequency signal detection, must be considered in the space of the formation of laser speckles, speckle pattern is a widespread statistical-optics phenomenon, it is the light is scattered through the media after the show is distributed. Doppler signal noise modulation, show as speckles Doppler frequency signal phase modulation or above, this paper is to analyze the laser speckles of remote sensing system of laser. Firstly introduces laser speckles causes and characteristics, this paper gives speckles probability distribution function, and the strength of the frequency function and speckles average diameter, the average length, Then with laser vibration, for example, according to the measured vibration of laser doppler principle and detailed analysis of the laser vibration of laser speckles of photoelectric detector output.
As the laser coherence, resulting in long-distance laser sensor syst
