High precision optical measurement requires the development and deployment of highly stable laser sources. The first step towards stabilising a laser is tracking and measuring it's phase noise. This project aims to develop new signal processing and optical methods to track and stabilise cheap noisy lasers for precision measurement.
A topic with a short-term Engineering project and Physics project, to investigate using optical single side-band modulators for interferometric measurements.
By leveraging hybrid digital-optical methods, we develop new distributed and quasi-distributed fibre-optic acoustic sensors. These acoustic sensors aim to measure vibration, strain and displacement all while localising the signal source along an optical fibre.
The project aims to develop methods to improve the sensitivity of optical metasurfaces for the detection of chemical and biological markers. By tailoring a high-precision optical interferometric sensing solution to the optical properties of a metasurface under-test, the project will improve the sensitivity of these devices, developing a new range of targeted ultra-precise metasurface sensors.
