1. A ladar transmitter apparatus comprising:

  • a first light source configured to generate a plurality of ladar pulses for transmission to a plurality of range points in a field of view;

    a second light source configured to generate a reference light at a different frequency than the ladar pulses;

    a plurality of mirrors that are scanable to a plurality of scan positions to define a targeting for the ladar transmitter apparatus in the field of view, wherein the scanable mirrors are configured to receive and direct the generated ladar pulses and the generated reference light toward a plurality of targeted range points in the scan area; and

    a dichroic photodetector that is optically downstream from the scanable mirrors, the dichroic photodetector configured to (1) pass the ladar pulses toward the range points, and (2) absorb and convert the reference light into a reference signal indicative of where the scanable mirrors are targeted when the ladar pulses are transmitted.
