Embodiment Construction
[0032] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0033] like figure 1 As shown, the ARM-based integrated polarization-maintaining fiber optic axis alignment instrument includes an image acquisition unit, an image processing and control unit 1, a motion actuator and a human-computer interaction unit.
[0034] The image acquisition unit includes a light source 7, a microscopic objective lens 9, a lens barrel 10, a CMOS industrial camera 11 and a microscopic camera 8;
[0035] The light source 7 obliquely illuminates the polarization-maintaining optical fiber 5 stripped of the coating at an angle of 30°-60° forward, the microscopic objective lens 9 and the polarization-maintaining optical fiber 5 are coaxial, and the CMOS camera 11 is connected to the microscopic objective lens 9 through the lens barrel 10. Micro camera 8 is fixed above the polarization maintaining fiber.
[0036] The motion actuator...
