Paper Abstract

The maximum rang finding ability of laser range finder (LRF) is greatly influenced by various factors under field conditions, and these factors are changing constantly. In this paper, the advantages and shortcomings of traditional test method 'dissipated light power ratio method' through field object target are analyzed. A computerized instrument is developed, this instrument has no influence with field environment and characteristics of targets, it is simple, effective, accurate and quantitative to test comprehensive ability of range measurement which LRF system itself has. This paper introduces optimal formulas by use of computerized instrument to estimate the measuring rang of LRF, studied the theory of equations of measuring range by laser, and made a breakthrough of test method at program control of time-delay simulating space range and transmission and receiving of LRF under field conditions. This computerized test instrument has highly practical application and theoretical guiding meaning in demarcating checking and accepting of product produced by factories.
