Abstract
A coherent range measurement system includes a detector optical arrangement defining a current optical field of view and an illumination subsystem configured for transmitting pulses of coherent illumination at different times along each of a plurality of directions within the current optical field of view without moving parts. A detection arrangement is configured to direct part of the transmitted pulses and a reflected signal from each of the directions onto a common detector. The output of the detector is processed by a processing system to derive range data associated with each of the directions by coherent detection of the reflected signals employing the part of the transmitted pulses as a local oscillator.
