Paper Abstract

A laser interferometer is described including a reference mirror mounted on a piezo-electric translator (allowing for follow-up control at low frequencies or scanning of the interference fringe system) and a Pockels cell which permits to modulate the phase of the reference beam and calibrate the apparatus. This interferometer has a sensitivity of approximately 0.01 nm and allows real time studies of the tympanic membrane displacements to be made in the living guinea pig undergoing the action of acoustic stimuli such as pure tones or impulse noise.
