The present paper analyzes the range determination 
error caused by the temperature instability in recirculation range 
finders of the simplest type, range finders with quartz frequency 
stabilization, and those based on a controlled injection laser. The 
analysis was performed taking into account the temperature dependence 
of the radiation power, the lifetime of nonequilibrium charge carriers, 
and the threshold current of the injection laser as well as the pulsed 
signal delay in the range finder's photodetector. It is shown that 
under the conditions of unstable temperature recirculation range finders 
based on controlled injection lasers have the least temperature component 
of the error in ranging.
