Background
In the fields of measurement, detection, instrument calibration and the like, the plane mirror needs to be adjusted to be horizontal, and then the plane mirror is used as a horizontal reference to carry out measurement, detection and calibration of other technical parameters.
Because the operation of directly adjusting the horizontal plane mirror reflection surface is complex, the plane mirror is arranged at the center of a rotary table which is provided with three lifting adjusting supporting legs and can freely rotate for 360 degrees, so that the reflection surface of the plane mirror is vertical to the axis of the rotary table, and the adjustment of the horizontal plane mirror reflection surface is indirectly realized by adjusting the axis of the rotary table to be vertical to the horizontal plane.
At present, the method of adjusting the inclination angle of a plane mirror by adopting a laser and a position detector is not very accurate in judging the posture of the plane mirror, and the uncertainty of an evaluation relation exists in the evaluation of the angle deviation by utilizing the position deviation.
First, the invariance of the position of the light spot reflected by the plane mirror onto the position detector within a certain range does not allow the size of the plane mirror tilt angle to be quantified, because the range of variation of the light spot on the position detector is not only related to the plane mirror tilt angle, but also to the distance between the position detector and the plane mirror. Different conclusions may be drawn for the same leveled mirror when the relative position of the detector and the mirror changes.
Secondly, calibration errors are brought by a certain divergence angle of light rays emitted by the laser, the shape of a laser spot and the non-perpendicularity between reflected light of the position detector and reflected light of the plane mirror.
