Non-mechanical High-Resolution Low-SWaP Lidar

This Phase II effort will be a proof-of-concept demonstration of a non-mechanical (no moving parts) 3D lidar system that provides in real time high-resolution terrain point cloud information. The objective is to build a compact sensor that meets the low size, weight and power (SWaP) requirements of planetary landers being developed for future NASA planet, moon and asteroid exploration. The lidar sensor will provide 5cm by 5cm by 5cm resolution over a 30-degree by 30-degree field of regard at a standoff distance of 1 km or more. This will be accomplished using a unique electro-optic scanner that provides the largest angle-aperture product of any commercially-available non-mechanical scanning technology.

The proposed low-SWaP lidar will have application in many NASA missions needing real-time 3D information such as fixing and refueling space craft, close approaches to asteroids, autonomous vision-based guidance and control for robotic systems and terrain mapping and hazard avoidance for autonomous land, air and sea vehicles. The technology developed in this project, especially the versatile non-mechanical beam scanning system, can be also tailored for other NASA sensor platforms such as coherent Doppler lidar for 3D wind sensing or differential absorption lidar (DIAL) for trace gas detection. Also, a reliable, low-SWaP gimbal replacement would also be useful for several other space-borne applications including active remote sensing using laser-based sensors, satellite-to-satellite communication, and position tracking within a cluster of nano-satellites, to name a few.

The proposed non-mechanical beam steering technology married with lidar sensors have numerous commercial applications. The platform can provide a low-SWaP package for hazard/collision avoidance for autonomous automobiles and unmanned vehicles, which is currently is gathering a lot of interest in the commercial sector. Other potential large markets are 3D imaging for autonomous robotics (factory automation), noncontact structure analysis, topographical mapping and gesture recognition for augmented reality systems. Additionally, the non-mechanical scanner technology is well suited to deployment on wind farms for guiding and controlling power-generating wind turbines. The sensor is particularly well suited for this application because the low-SWaP package is ideal for mounting directly to a turbine or even packaging in an ocean-going buoy for sea-based wind farms. Such a buoy network would also have weather warning and prediction applications. Within the Department of Defense, this technology is being developed for applications such as munitions seeker tracking, passive imaging, and conventional hard-target lidar. Also, there is interest from automotive manufacturers who wish to use the technology for non-mechanical headlight steering.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
