Abstract
A Michelson interferometer has been developed which uses a right-angled prism mirrored on the sides containing the right angle, to measure small tilt angles with double sensitivity compared to the classical Michelson interferometer. The design of the interferometer, theory, relative sensitivity as well as experimental results are presented. With this setup, we could measure tilt angle up to 1 \(\mathrm{\mu rad}\).
