Compact High-Performance Laser Gyro

The rotation sensitivity of a conventional optical Inertial Navigation System (INS)depends on the area enclosed by a circular optical path. Hence, it is impossible to significantly reduce the device size without sacrificing its sensitivity. Recent work showed that certain non-linear optical effects (fast light) can be used to increase the sensitivity of a ring laser gyro of a given size by orders of magnitude. We propose a portable high-performance all-fiber laser gyroscope. The device will utilize fast light produced by the Stimulated Brillouin Scattering in single-mode fibers. Fast light enhancement will enable reduction of the device size without decreasing its performance level. The fast light enhanced gyroscope will empower a rugged, compact, low-cost high-sensitivity INS ideal for precision guiding of UAVs, and other aircrafts.

-Precise control and positioning of the UAVs. -Aircraft navigation -Tracking and control of launch vehicles for placing payloads into orbital or sub-orbital trajectories. -Precision inertial feedback during orbital maneuvers or station keeping operations on manned or unmanned spacecraft. -Actively stabilize instrument platforms during sensitive astronomical observations or scientific measurements.

-Self-guided ordinance and unmanned aerial vehicles, where traditional high sensitivity optical INS systems are too large to use. -Stabilizing weapons platforms or communications devices mounted on ground and naval vehicles of all sizes. -Commercial aircraft and marine vessels commonly use optical inertial measurement devices for navigation, stabilization, and tracking.

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.
