Paper Abstract

In the paper, the authors discuss an increase of the precision of a laser interferometer for measurement in the subnanometer range, for example, for refractometry and ultra-high precision measurements. There are two methods of the detection of interferometer fringes. One type applies the heterodyne principle with the frequency subtracting and the two-frequency laser. The other type is based on the amplitude division of the fringe and on the single-frequency laser. The paper deal with the latter type of the interferometer.
