Applications

AOSense designs, fabricates, and tests high-performance cold atom sensors for inertial navigation, gravity measurement, and time and frequency standards. We are dedicated to commercializing these technologies for defense, industrial, and scientific applications. Cold atom sensors can be tailored to a wide range of applications, and often outperform traditional sensors by orders of magnitude. AOSense can also provide component-level building blocks such as lasers and atom sources. Please contact us to discuss your precision sensor needs.

Precision timekeeping - silver pocket watch

Time & frequency standards

Precise time and frequency synthesis underlies modern communication, radar, and navigation systems. Recently, lab-based optical atomic clocks have demonstrated orders-of-magnitude improved performance over traditional microwave standards as are used in GPS due to the higher quality factor for optical atomic transitions. Currently, AOSense is developing portable optical frequency standards and self-referenced frequency combs designed for simplicity and ruggedness. Parallel efforts seek to improve upon microwave clocks by implementing techniques such as laser cooling and trapping.

Inertial sensors

Navigating in environments where GPS is unavailable or actively denied is a critical challenge for modern military and commercial platforms. Currently, AOSense is designing and building high-performance inertial navigation sensors to precisely determine location in the absence of any external signals. AOSense can provide numerous inertial sensor configurations customized for specific military and industrial requirements, including gyroscopes, accelerometers, and inertial measurement units (IMU).

Geodetic & geophysical sensors

High-performance gravimeters and gravity gradiometers are well-suited for geophysical surveying, including oil and mineral exploration, underground fluid monitoring, and mapping seabeds. Such sensors may also be useful for identifying special nuclear materials, treaty verification, and void detection. AOSense has built and demonstrated cold atom sensors for measuring gravity and gravity gradients, including a compact gravimeter that we shipped to an aerospace customer.
