Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] The invention discloses an interference calibration system, which comprises a moving mirror drive device, a laser interference calibration system and a moving mirror control circuit.
[0027] Such as figure 1 As shown, the moving mirror drive device includes a stepper motor 101 fixed at one end of the support base 102 and a ball screw 105 connected to the output shaft of the motor through a coupling 103. The stepper motor 101 is a two-phase hybrid stepper Motor, the step angle is 1.8°, the stepper motor 101 drives the ball screw 105 to rotate, the backlash and frictional resistance of the ball screw 105 are very small, the inner side of the support base 102 is fixed with a cross roller guide rail 104, on the cross roller guide rail 104 A slider 106 connected to a ball screw 105 is installed, and the cross roller guide 104 is a linear guide device in w...
