Apparatus for measuring acceleration by double optical beams, optical fibers and light traps

Abstract

The invention discloses a device which uses a dual-beam optical fiber light trap to measure acceleration. The device comprises an optical maser, a light intensity modulator, two single mode fibers, a capillary glass tube, a photonics image detector and a processor which are arranged on a substrate; wherein, light sent out from the optical maser is modulated into two beams of light with same intensity and then respectively input in the two single mode fibers; and the output ends of the two single mode fibers are respectively fixed at the two ends of the capillary glass tube; and the caliber of the capillary glass tube is matched with the output end of the single mode fiber; a ball-shaped SiC particle is arranged in the capillary glass tube. The device provided by the invention is fixed on the main body of a measured object, and when the main body of the measured object is in accelerated motion along the direction of optical axis, the particle is going to deviate from the original balance position. The photonics image detector measures the position of the particle, and a corresponding adjustment value can be worked out by the processor, and then the light intensity modulator changes the output light intensities of the two beams of light according to the measured position of the particle and the obtained adjustment value to let the particle return to the original balance position. According to the light intensity differences of the light intensity modular, the processor works out gained acceleration.
