  • Abstract
    The use of a spherical mirror Fabry¿Perot (confocal) interferometer as an optical displacement sensor is described. The device incorporates a simple electronic servo to maintain the interferometer at an operating point of maximum sensitivity. Applications as vibration and acceleration sensors are forseen, with sensitivities for sinusoidal accelerations of 10¿3 ¿g achievable at 10 Hz.
