3D sensor development to support EDL (entry, descent, and landing) for autonomous missions to Mars

摘要

Tetra Vue developing a Megapixel-class 3D camera system that uniquely addresses autonomous spcecraft requirements for a situational awareness seness sensor during the pianetary landing phase.TetraVuse systen uses a novel approach to FLASH LIDAR which utilizes existing commercial off-the-shelf(COTS)focal plane arrays in a single apeture module.The system is flexible enough to adapt to different resolution requirements withoutre reinventing the hardware architecture or develop new imaging sensors with cutom readout circuitry.Since the system uses a nanosecond-class laser as an illumination source,similar to a strobe,the data is insensitive to motion which makes it ideally suitable for landing site selection.
