Abstract
An optical imaging system is provided with a pulsed laser rangefinder comprising a transmitter 10 aligned with the boresight of the imaging system, the return pulse being focussed by the telescope 6 of the imaging system upon its multi-mirror, two-rotor arrangement 2, 3 and reflected then to a detector 12 and display 13. To eliminate the effect of rotor rotation during the time-of-travel of the pulse, the latter is first reflected from the rotors to a beam reverser 14 including a 90 degree roof-reflector 18 (FIG. 2), which reflects the pulse back to the rotor mirrors in the same vertical plane and then to detector 12 along a path having a fixed spatial relationship to the path to the imaging-system detector 8.
