ABSTRACT:
The telemeter e.g. for tanks or aeroplanes, includes in particular a diaphragm disposed in the optical receiving system, the diaphragm is provided with closing means which operate outside the period during which a measuring echo is expected so as to protect the receiver of the telemeter against any interference light pulse (except during said measuring period). This reduces the risks of serious damage to the receiver from counter-measure laser pulses.
