由于激光的相干性,导致在远距离激光传感系统中和探测差频信号时,必须要考虑到激光在空间形成的散斑的影响,散斑是一种普遍存在的统计光学现象,它是光波经过介质的无规散射后呈现出的无规分布.Doppler信号调制中,散斑噪声即表现为Doppler信号的相位调制或频率展宽,本文重点是分析激光散斑对远距离激光传感系统的影响.首先介绍了激光散斑产生的原因及特点,从理论上给出散斑强度的概率分布函数、频率函数和散斑的平均直径、平均长度；然后又以激光测振仪为例,根据激光测振多普勒原理,详细分析了激光测振仪中激光散斑对光电探测器输出的影响.

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.
