| 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 t ,then ,while SNR t is a minimum, the signal-to-noise ratio is selected as an optimum and the laser beam divergence is selected synchronously as an optimum. |

| Keywords: | optimum signal-to-noise ratio laser beam divergence laser range-finder |
