Abstract:
     This invention relates to grating strain-gauge rosette processing method in optical technique field, which comprises the following steps: computing and generating two beam center lines half and splitting one beam laser into two through split lens and putting one reflection lens with equal distance along the sending direction and locating one rotation platform in the angle bisector and adjusting reflection lens to make the two beam focus on the center of workbench; locating the holography board on the rotation workbench to determine best exploring time; opening shot and making the first exposure to rotate workbench to needed angle and opening shot for second exploring; then making the third exploring through developing.
