The present application relates to the field of optical measurement technology, and particularly to an
optical alignment verification system and method. The
system comprises a
collimator, a
light source module, a guide rail, a camera, a scanning element, a slide, an
image processing module, a reference calibration module, a deviation determination module and a visual
graphical user interface. The method is based on the above
system, first acquires the
light spot images at two different positions on the guide rail, obtains the
light spot center coordinates, the
reference line and the theoretical center point of the
reference line; adjusts the posture of the
collimator, calculates the deviation between the measured
light spot center coordinates and the theoretical center point, generates a quantitative adjustment suggestion according to the deviation, physically adjusts the
collimator until the deviation meets the preset threshold condition. The present application integrates light spot measurement, deviation evaluation and adjustment guidance functions, can quickly and actively suppress the beam transverse shift error, and solves the problem of insufficient initial measurement accuracy and inability to effectively implement subsequent error suppression of the traditional method.
