On construction of laser acousto-optical heterodyne interferometers with push-pull measurement of product motions

The article discusses the implementation of a differential pushpull measurement method using a phase interpolator and a phase meter in an acousto-optical (AO) heterodyne laser interferometer of displacements (in future –a laser interferometer). To reduce the noise level in the measuring signal, a...
