AbstractAdvanced Scientific Concepts, Inc. (ASC) is a small business, which has developed a compact, eye-safe 3D Flash LIDARTM Camera (FLC) well suited for real-time spacecraft trajectory, speed, orientation measurements relative to the planet's surfaces and evaluating potential hazards during the critical landing sequence. Data collected using ASC's FLC at JPL's Mars Yard and in NASA ALHAT flight tests demonstrated that ASC Flash LIDAR system can meet the requirements for Entry Descent and Landing (EDL). Aboard the Space Shuttle Endeavour (STS-127), SpaceX and ASC demonstrated the DragonEye Autonomous Rendezvous and Docking (AR & D) Flash LIDAR solution in low earth orbit, the first Flash LIDAR in space. ASC is developing a camera for iRobot Corporation for use in autonomous robotic navigation which is directly applicable to EDL mission requirements. ASC will develop hybridization process improvements and process controls to increase the lifetime and pixel operability of the 3D-FPA. Current 3D-FPA hybrids see degradation in harsh environments. Shock, vibration, humidity and temperature cycles are all of concern. Improved assembly processes for the hybrid in the hermetic package will allow for improved operability, yield and lifetime. ASC's 128x128 3D array FLC has the equivalent of 16,000 range finders on a single FPA which allows the sensor to act as a 3D video camera with enhanced functionality and value add well beyond range finding.
