PIXIE Precision Technology Demonstration

Completed TRL 4 (started at 4, targeting 4)

Description

The Electro-Thermal Characterization of a Multi-Moded Bolometer characterize the electrical and thermal performance of large multi-moded bolometers for a new generation of far-infrared instrumentation. Multi-moded systems provide distinct advantages compared to current single-moded designs. By collecting more photons on each detector, multi-moded designs improve sensitivity by an order of magnitude. One multi-moded detector can thus replace 100 single-moded detectors, providing two orders of magnitude reduction in detector count while simplifying instrument design, integration, and testing.

The project work will test a far-IR detector with 30 times the absorbing area as the bolometers flown on the Planck mission. Multi-moded systems provide distinct advantages compared to current single-moded designs. By collecting more photons on each detector, multi-moded designs improve sensitivity by an order of magnitude. One multi-moded detector can thus replace 100 single-moded detectors, providing two orders of magnitude reduction in detector count while simplifying instrument design, integration, and testing.

Additionally, we will extend the detector capabilities to include the much higher optical loads encountered during use in stratospheric balloon payloads.

Benefits

By reducing the number of detectors required for photon-limited applications, the multi-moded bolometer can decrease the cost of detector and readout systems by a factor of ten or more.

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.
