A description of a Fabry-Perot interferometer for measuring small displacements is given. The instruments consists of a fiber-optic-coupled actuator and mirror guiding mechanisms, a tunable diode laser for tracking the changes in cavity length and a reference laser for heterodyned laser frequency measurements.
