[0055] Example
[0056] Such as figure 1 As shown, the present invention consists of liquid crystal touch screen 1, precision micro-displacement control devices 3, 6, 7, pressure applying device 2, optical path system, optical fiber transmission polarization state direct coupling adjustment device 3, 12, light source drive module 5, signal processing The analysis control system 8, the detector and the optical power detection module 10, and the upper computer analysis processing system 11.
[0057] The LCD touch screen is used in a human-computer interaction platform to input control parameters and display measurement data and measurement results. It is connected to the signal processing analysis control system 8 through interfaces 24 and 16. The pressure applying device 2 is connected to the screw nut 9 in the precision displacement control device. As the screw nut moves left and right, the optical fiber clamped between the bearing pair is subjected to a predetermined pressure, a...
