Fabry-Perot for the Integrated Direct Detection Lidar (FIDDL)
Completed
TRL 4 (started at 2, targeting 4)
Description
Develop an etalon front end receiver (FIDDL) and combine it with the Optical Autocovariance Wind Lidar (OAWL) for an integrated direct detection (IDD) wind lidar. Demonstrate the IDD hybrid system measuring winds from both molecular and aerosol returns using a single lidar. The hybrid system will significantly reduce the size and cost of a 3D Winds mission (on the order of 20-30% based on aperture size) compared to the current hybrid 2-laser approach. Performance goals are < 1 m/s wind estimate precision for the etalon sub-system.

How to get involved
This is early/mid-stage (TRL 4) — 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.
