Laser interferometers for measuring displacements and determining object positions.
Laser interferometers for measuring lengths, gas refraction indexes, and laser wavelengths and for determining relative object positions have been developed. The instruments are based on a traditional principle of fringe-counting interferometers; for the determination of positions a reversed aperture interferometer sensitive to light-source displacements has been used.
