Terrestrial Planet Finder Coronagraph High Accuracy Optical Propagation, Phase I

The Terrestrial Planet Finder (TPF) project is considering several approaches to discovering planets orbiting stars far from earth and assessing their suitability to support life. One of these approaches is based on a coronagraph design operating in the visible wavelength regime, which requires both very high surface quality, large aperture, telescope optics and advanced optical systems to reject direct, scattered and diffracted starlight that is on the order of 1x109 brighter than the light reflected from the planet. The project has the need for advanced optical modeling and design tools that include physical optical calculations to support propagation results at a contrast level of 1x10-11 at the image plane of the coronagraph. The CODE V software is the most advanced software available for a wide variety of state of the art optical engineering tasks, and would be ideally suited for the TPF project once the proposed capabilities are integrated. Optical Research Associates proposes to extend capabilities of a newly researched method for beam propagation to support the optical system modeling needs of the TPF coronagraph project. The result will be an optical design and analysis tool to provide another means for predicting the performance of this important astronomical asset.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
