【Abstract】 The problem how to select optimum of signal-to-noise ratio and laser beam divergence for laser range-finder is studied. If signal-to-noise ratio is expressed as SNR and laser beam divergence is expressed as θt,then,while SNR θt2 is a minimum, the signal-to-noise ratio is selected as an optimum and the laser beam divergence is selected synchronously as an optimum.更多还原
