DEVICE AND METHOD FOR MEASURING ACCELERATION ON AN OPTICAL DISCHARGE BY THE SHADOW METHOD Russian patent published in 2022 - IPC G01P15/00 

FIELD: instrumentation.

SUBSTANCE: group of inventions relates to the field of instrumentation. The device for measuring acceleration on an optical discharge by the shadow method consists of a spherical chamber, transparent to laser and visible radiation, filled with a gas mixture; one or more lasers located outside the spherical chamber, the radiation of which is focused in the center of the spherical chamber, two spherical mirrors are installed perpendicular to each other outside the spherical chamber, and on the opposite side of the spherical chamber, opposite each spherical mirror, there is a translucent screen for visualizing the shadow image of the heat flux, while at least four photo sensors are installed on each translucent screen.

EFFECT: extension of the acceleration measurement range and an improvement in the speed of acceleration measurement.
