This project develops fibre optic instruments based on optical interferometry and digital signal processing for the purpose of inertial navigation.
This project has a strong industry focus and investigates using an array of interferometers for acoustic sensing. It relies on the ultra-sensitivity of these devices and the array's ability to triangulate the source of an acoustic signal to target a range of applications.
Recent advances in laser technology now enable the combination of multiple high-quality lasers into a single high-power beam. The aim of this project is to investigate such `coherently-combined' laser systems within the context of Earth-to-Space laser transmission. Applications of this technology include satellite laser ranging, clock transfer and free-space optical communications, and space debris tracking and remote manouevring.
Using an atomic clock and an optical frequency comb as diagnostics, this project investigates laser stabilisation using an optical fibre interferometer for field deployable applications such as in space-based instruments.
