Title: Two-beam interferometer
Inventor: Ugozhaev Vladimir Dmitrievich
IPC: G01B9/02
Filed: 2018-07-23
Granted: 2019-08-21
Abstract: FIELD: instrument engineering. 
     SUBSTANCE: proposed invention relates to optical holography and is intended for generation of periodic interference patterns. Rotationally tunable double-beam interferometer designed to generate periodic interference patterns comprises a source arranged in series along the radiation path, beam-splitting element performing two functions which are necessary and sufficient for a double-beam interferometer: splitting of the initial beam into two partial and subsequent their reduction at a given plane under a variable convergent angle, and a photodetector. Light-splitting element with built-in divider mirror and photodetector are mutually fixed and together form a system, which is mirror-symmetrical relative to plane of this divider mirror. Photoreceiver is placed inside the interference region, which in the process of rotational readjustment of the angle of convergence of the partial beams undergoes a shift, which is small compared to the longitudinal size of the given region. Latter is provided by mutual matching of change of angle of incidence of the initial beam to the divider mirror and its movement along this mirror. Control unit generates control signals for rotary motion drive corresponding to this matching law. 
     EFFECT: high vibration resistance, high contrast depth of the recorded holographic diffraction gratings and high accuracy of measuring wavelengths when detecting spectra of electromagnetic radiation when the disclosed interferometer is used as a static Fourier spectrometer.

At supply of foam a stable layer of foam of average multiplicity, having high fluidity and fire-extinguishing properties is formed. According to the proposed technical solutions, the entire range of barrels can be made with consumption in solution of 20 to 150 l/s, which enables to almost completely solve the task of mastering and implementing a new technology for extinguishing large fires of classes B (and A) with foams with Kp = 30 ± 10, LH-GH, including at large reservoirs of RVS type. This will make it possible to eliminate deficiency in the country of foam generators of homogeneous foam with multiplicity Kp = 30 ± 10, which provides maximum efficiency of suppression of large fires of the specified type. 
     EFFECT: creation of device with continuous and sprayed jets on water and foam with variable spraying angle, which generates and supplies single-flow foam with improved ballistic indices in range, forming foam of average multiplicity of increased fluidity, simplified design, with reduced size and weight and reduced hydraulic losses.
