Completed TRL 4 (started at 1, targeting 4)
We propose to develop the high-level specifications for an image-based wavefront sensing instrument for a post-decadal survey LUVOIR-type mission. Such an instrument could remove the need for the edge sensors and laser metrology system in the current concept and enable closed loop image-based control.
In the context of LUVOIR-like future missions, a phase retrieval-based wavefront sensing instrument could remove or reduce the need for two technologies: segment-to-segment edge sensors and a laser metrology system monitoring the secondary mirror. This would reduce risk and technical complexity and thus cost. Also, directly measuring optical performance reduces the risk of unsensed drifts or creep between a physical reference (like an edge sensor) and the mirror surface. The picometer wavefront control capability this contributes to is an enabling technology for the LUVOIR concept.
Listed on TechPort itself — the most direct way to ask about this specific project.
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.
