Device and method for measuring birefringence phase difference of intelligent microscopic imaging crystal

The invention relates to an intelligent microscopic imaging crystal birefringence phase difference measuring device and method, the device comprises a measuring device main body, a laser light source part and an acquisition part, linear polarization laser emitted by the laser light source part passes through the measuring device main body, and a rotary stepping motor changes the linear polarization direction of a laser light source; the light intensity of linearly polarized laser in different directions is modulated by using the birefringence effect of the crystal, and the birefringence characteristic of the crystal is calculated by collecting a plurality of light intensity distribution diagrams of the laser modulated by the birefringence of the crystal in different linear polarization directions. According to the device and the method for measuring the birefringence phase difference of the intelligent microscopic imaging crystal, the birefringence information of the crystal is represented through the change
