Paper Abstract

We present a modified scheme of an optical heterodyne interferometric microscope. Reference signal is taken from a low-frequency generator rather than a photodiode to improve stability. Slit aperture is introduced to increase the detected signal. Frequencies of acoustic waves applied to the Bragg cell are adjusted to improve spatial resolution.
