FIELD: measuring technique.
SUBSTANCE: method comprises transmitting and receiving of a polarized beam containing two different wave lengths, modulating the beam, splitting the beam into two beams, converting the beams into the normalized electric signals, and calculating the angle of mutual orientation of objects. The spectral components of the beams of two waves are linearly polarized, collinear, and orthogonal.
EFFECT: enhanced precision.
