FIELD: physics.
SUBSTANCE: device has tank with liquid. Above liquid objective is mounted, light-dividing element, light source and position-sensitive photo-detector, video-frame with video image of light source. Light-dividing element is mounted on optical axis of objective and separates this on two axes. Tank incline angle is recorded in directions of appropriate coordinate axes.
EFFECT: broader functional capabilities, higher precision.
