Paper Abstract

TetraVue is developing a MegaPixel-class 3D camera system that uniquely addresses autonomous spacecraft requirements for a situational awareness sensor during the planetary landing phase. TetraVue's system uses a novel approach to FLASH LIDAR which utilizes existing commercial off-the-shelf (COTS) focal plane arrays in a single aperture module. This makes the system flexible enough to adapt to different resolution requirements without reinventing the hardware architecture or develop new imaging sensors with custom readout circuitry. Since the system uses a nanosecond-class laser as an illumination source, similar to a strobe, the data is insensitive to any discernable cross-motion which make it ideally suitable for landing site selection during the horizontal coast phase.
