DEVICE FOR MEASURING LINEAR AND ANGULAR DISPLACEMENTS, VELOCITIES AND ACCELERATIONS OF OBJECTS Russian patent published in 2022 - IPC G01B21/00 

FIELD: measuring equipment.

SUBSTANCE: invention is intended to improve the accuracy, reliability and speed of noise-proof measurements of movement parameters of rolling parts of artillery systems at high rollback-roll forward speeds. A device for measuring linear and angular displacements, velocities and accelerations of a rollback part of an artillery system contains a source of information modulated light radiation, a reflecting mirror, two coordinate photodetectors optically connected to it, an electronic circuit. At the same time, coordinate photodetectors are made in the form of two discrete-continuous multi-scans arranged symmetrically along a horizontal line perpendicular to the direction of movement of the rollback part of the artillery system, on which half mirrors are installed to reflect an information modulated light flux onto discrete-continuous multi-scans. The electronic circuit contains two sources of calibration modulated radiation optically connected to two discrete-continuous multi-scans.

EFFECT: simultaneous registration of linear displacements and angular misalignments of rollback parts at high rollback-roll forward speeds, as well as improvement of metrological characteristics due to the use of modulation mode with alternating switching on of radiation sources for the formation of information and calibration light zones on photosensitive surfaces of discrete-continuous multi-scans.
