FIELD: instrument engineering.
SUBSTANCE: interferometer refers to navigational engineering and is designed to work on a mobile base of an absolute gravimeter. Interferometer contains a test body with an angled reflector, reference and a measuring beam, combined at one point of the screen. On the path of the measuring beam, an optical system is installed, guiding it to the point of intersection with the reference beam, regardless of the horizontal displacement of the angle reflector. Proposed interferometer removes restrictions on the conditions of navigation and placement of an instrument on a ship in the process of absolute gravimetric measurements at sea.
EFFECT: higher accuracy of the gravimeter and improved operational characteristics.
