✦ Synopsis

In order to measure small-angle rotations, the two mirrors of a Michelson interferometer are replaced by right-angle prisms. By increasing the distance between the two prisms and by means of an electronic fringe divider technique, the resolution can be increased to 10 5 degree, with a range of measurement from + 5 Β° to -5 Β°.

Single-mode optical fiber interferometers used with measurement or sensing systems should be stabilised to achieve high measurement accuracy and linearity in the presence of differential phase drift in their arms resulting from temperature fluctuations and other types of environmental disturbances.
