More details about the invention

FIELD: monitoring and measuring equipment.
SUBSTANCE: invention relates to instrumentation and relates to the device for measuring inclination angles of the surface. The device includes a single-mode stabilized laser source fixed on the platform, a cuvette with a viscous dielectric liquid located on the path of the laser beam, a position-sensitive photodetector with a signal recording unit serving to determine the position of the laser beam reflected from the surface of the liquid. Besides, device additionally comprises plane-parallel optical plate located on the path of the beam and connected to platform, intended for reflection of part of the laser beam, located on platform second position-sensitive photodetector with recording unit, used to detect the signal of angular noise motion of laser beam, and a processing unit serving to subtract the laser beam angular noise motion signal from the main signal.
EFFECT: technical result is the higher sensitivity of the device.
