小型低值LD激光测距仪的测距能力与系统的信噪比

THE ABILITY OF MEASUREMENT DISTANCE OF LOW COST MINI LD LASER RANGEFINDER AND THE SIGNAL NOISE RATE SNR OF SYSTEM

研制成一种小型、便携式、低值、对人眼安全、无合作目标的小型低值半导体ＬＤ激光测距仪．工作波长λ＝９０５ｎｍ；测距范围１４～１０００ｍ；测距精度＜±１ｍ；重复频率１００Ｈｚ．有多种工作模式，具有省电功能．它的测距能力优于国内外同类低值ＬＤ激光测距仪．ＬＦ－１激光测距仪是一种光子雷达系统．本文从光子测距方程、系统结构、信噪比分析角度。

LF 1 series LD laser rangefinder (LRF) have been made,the LRF is a miniature,low cost,eye safe,no cooperation target.The main performance of LF 1 series laser rangefinder:laser wavelength:λ=905nm;measurement distance range:14 1000m;accuracy of measurement:<±1m;repetition frequency:100Hz;it have multi operation model and save electric function.The measurement distance ability is better than same type low cost LD LRF.LF 1 LRF is a photon radar system,the ability of measurement distance of the system have been discussed according to the photon measurement distance equation,the configuration of system,signal noise ratio.
