Embodiment Construction
[0019] The patent of the present invention adopts the following technical scheme: a new type of quartz flexible accelerometer based on laser self-mixing interference, including a meter head and a digital rebalancing circuit. The head is composed of a shell, a pendulum assembly, a torque device, and a laser. The digital rebalancing circuit includes a laser drive power supply, a photoelectric detection circuit, a data acquisition circuit, a digital signal processing circuit and a torque current generator. When there is an acceleration input, the laser self-mixing interference signal sensor detects the displacement of the pendulum assembly and converts it into an electrical signal. The electrical signal is converted into a current signal proportional to the acceleration through a digital rebalance circuit, and fed back to the torquer to generate Rebalance the torque, and the acceleration can be obtained by detecting the current of the torque device.
