DEVICE FOR DEFORMATION MEASURING Russian patent published in 2022 - IPC G01B11/16 

FIELD: solids deformation properties measuring.

SUBSTANCE: invention relates to the field of methods for measuring the deformation properties of solids, in particular to devices for remote and non-contact measurement of deformation and deformation rate of solids in a continuous mode, and can be used in various sectors of the national economy for non-destructive remote monitoring in "real time" of objects and products located in areas inaccessible to service personnel. The claimed device for measuring deformation contains a laser, an optical scheme and a system for recording and processing measurement results. The optical scheme includes: the first semitransparent mirror, which provides the separation of the light flux into reference and probing light beams, the second semitransparent mirror, two light reflectors, a movable mirror rigidly connected to the controlled object, a polarizer and two photodetectors, and in the direction of propagation of the reference light beam, the first semitransparent mirror, two light reflectors, then the second semitransparent mirror, the polarizer and the first photodetector are located in series, and in the direction of propagation of the probing light beam, the first semitransparent mirror, then the movable mirror, the second semitransparent mirror and the second photodetector are arranged in series. In this case, the signal from the photodetectors is fed to the system for recording and processing measurement results, which allows high-precision, remote and non-contact measurement of the magnitude and rate of deformation in a continuous mode, which includes: a data collection device and a personal computer with software that includes programs for receiving and processing data.

EFFECT: simplification of the process of measuring the amount of deformation, carrying out measurements in a periodic mode, simplifying the interpretation and processing of recorded interference patterns, the ability to determine the amount of deformation and the rate of deformation in one dimension.
