This self-directed course will explore how various optical techniques can be utilised for metrology. Online materials will introduce the theoretical description of interferometers and discusses different configurations for metrology. Interferometer phase recovery is discussed. The course explores how they can be utilized for fundamental length metrology, and deployed to engineering applications such strain and temperature sensing. Optical sources are a core element of any interferometer, and the stabilisation of lasers and their applications is discussed, including highlighting the advantages and challenges of semiconductor lasers compared to traditional gas lasers.
This distance learning course is operated by Heriot-Watt University via their Canvas virtual learning environment. To complete the course students must carry out an online assessment using the Canvas system, which means they must first apply for an account. Details for doing this appear on the OMY my.SUPA page. SUPA students must first register on my.SUPA by Monday 18 January 2027, after which they will receive Canvas log-in details. Registration will be closed after this deadline.
