Abstract: Various embodiments are disclosed for improved scanning ladar transmission, including but not limited to an example embodiment where the scanning ladar transmission system includes a spinning polygon mirror for targeting range points according to a dynamic scan pattern.
Abstract: Various embodiments are disclosed for improved scanning ladar transmission, including but not limited to an example embodiment where a dynamic scan pattern for a scanning ladar transmission system includes a macro pattern having a base pattern embedded therein.
Abstract: Disclosed herein is a scanning ladar transmitter that employs an optical field splitter/inverter to improve the gaze characteristics of the ladar transmitter on desirable portions of a scan area. Also disclosed is the use of scan patterns such as Lissajous scan patterns for a scanning ladar transmitter where a phase drift is induced into the scanning to improve the gaze characteristics of the ladar transmitter on desirable portions of the scan area. Also disclosed is a compact beam scanner assembly that includes an ellipsoidal reimaging mirror.

Abstract: Disclosed herein are various embodiments of an adaptive ladar receiver and associated method whereby the active pixels in a photodetector array used for reception of ladar pulse returns can be adaptively controlled based at least in part on where the ladar pulses were targeted. Additional embodiments disclose improved imaging optics for use by the receiver and further adaptive control techniques for selecting which pixels of the photodetector array are used for sensing incident light.
