LASER-INTERFERENCE VECTOR RECEIVER Russian patent published in 2019 - IPC G01H3/00 G01L11/04 

FIELD: hydro acoustics.

SUBSTANCE: invention relates to hydro acoustics, namely, to combined vector receivers and can be used for vector-scalar measurements of parameters of ocean hydroacoustic fields. Receiver includes a spherical body with zero-zero buoyancy, which is installed in the holder by means of elastic elements. Along the axes of the rectangular coordinate system there are four flat mirrors which are reflectors of measuring beams of laser interferometers installed on the holder. Two mirrors are located on one axis on different sides of spherical body, and two others are arranged each on one of remaining axes.

EFFECT: technical result consists in wider operating frequency range, high noise immunity, as well as possibility of measuring submersion depth receiver.
