Using a method of mathematical simulation, it is shown 
that the maximum range measured by a GaAlAs injection-laser-based 
recirculating optical range finder decreases linearly with increase 
in the environment temperature. The steepness of its decrease depends 
on the excess of the laser injection current over a threshold value. 
At temperatures nearly equal to room temperature, the maximum measured 
range increases nonlinearly with increase in the injection current, 
and for I > 2.5Ithr this dependence is 
close to saturation, but it decreases nonlinearly with increase in 
the divergence angle of the injection laser radiation.
