DragonEye 3D Flash LIDAR Space Camera™

 

The DragonEye Space Camera™ is a lightweight, small form-factor (11.2 x 11.9 x 12.2 cm) integrated 3D FLC, capable of capturing a full array of 128x128 independently triggered pixels per each frame up to 10 frames per second, allowing 16,300 3D range data and intensity points to be generated as 3D point cloud images or video streams in real-time.  Designed for NASA’s Commercial Orbital Transportation Services (COTS) applications and working with Space Exploration Corporation, the DragonEye is the right sensor for Automated Rendezvous and Docking (AR&D) with the International Space Station and On-orbit Satellite Servicing.  The DragonEye has been tested on NASA’s STS-127 (Endeavour Obiter) and is mounted currently on the STS-133 (Discovery) for a round of pre-deployment tests.  This is the same 3D camera sensor engine being used by NASA Langley Research Center as the core 3D Flash LIDAR sensor engine for the Autonomous Landing and Hazard Avoidance (ALHAT) efforts.

The DragonEye consists of three primary components, the (A) 3D sensor engine, the (B) laser illuminator with lens/diffuser and the (C) cooling surfaces/vacuum enclosure.
