FIELD: instrument.SUBSTANCE: accelerometer comprises a cell of two polarisers set in parallel with the sensor element between them, made of transparent strain-sensitive material - polyurethane having a wedge shape. The force on the strain-sensitive element from the inertial element is transmitted by double lever system consisting of cargo under the action of the measured micro-acceleration, the leverage resting on the supports and the sites acting on the sensor element. To determine the number of interference fringes the web camera is used, mounted on one side of the cell, on the other side of which the highlighter of opal glass and LED light source is mounted for uniform illumination, at that a spring is mounted to protect the system from overload in the area of cargo under the action of the measured micro-acceleration.EFFECT: increase in sensitivity and accuracy of measurement, the ability to conduct measurements under conditions of a space station.2 cl, 1 dwg |
