A dual mode LADAR/SAL apparatus is disclosed. In one aspect, the apparatus includes a gimbal capable of scanning in azimuth and in elevation and a sensor mounted on the gimbal. The sensor includes a telescope, a LADAR optical path, and a SAL optical path. The telescope defines an exit pupil through which the sensor collects reflected light. The sensor further includes means for directing light received through the telescope to the LADAR optical path in a first position and to the SAL optical path in a second position such that the SAL optical path receives the collected light from the exit pupil of the telescope. The means may be, for example, a mirror. In a second aspect, an apparatus includes a gimbal capable of scanning in azimuth and in elevation, and a sensor mounted on the gimbal. The sensor includes a telescope defining an exit pupil through which the sensor collects reflected light. The sensor is capable of operating in a LADAR mode and in a SAL mode and receiving collected light in the SAL mode through a limited portion of the exit pupil.
