【摘要】 研制成一种小型、便携式、低值、对人眼安全、无合作目标的 Ｌ Ｆ１ 系列半导体 Ｌ Ｄ 激光测距仪。工作波长为９０５ ｎ ｍ ；测距范围是１４ ｍ ～１ ０００ ｍ ；测距精度小于±１ ｍ ；重复频率为１００ Ｈｚ 。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 Ｌ Ｄ 激光测距仪。本文从光子测距方程、系统结构、信噪比分析角度，讨论了系统的测距能力更多还原

【Abstract】 Series LF1 portable LD laser rangefinder(LRF)has been successfully developed featuring Small sizee,low cost, eye safety, and with no cooperation target.Its wavelength( λ )is 905 nm, with the ranging range of 14 m～1000 m,accuracy of less than ±1 m and repetition frequency of 100 Hz. There exist various operation modes with the function of power saving.The ranging ability is superior to that of overseas countepart LF1 LRF is a kind of photonic radar system.The ranging ability of the system is discussed on the basis of the photonic ranging equation, the system configuration,and signal noise ratio.更多还原
