Research on In-situ Measurement System of Microstructure Array
The quality of the light guide plate is determined by the accuracy of the microstructure array pro-cessed on the light guide plate mold steel. In the process of precision hitting machine processing light guide plate mold, the processing of the microstructure of the array is in-situ measurement, if the light guide plate mold was removed and then back to the machine, the processing conditions had changed, there was no meaning hitting the follow-up points. The aperture measurement and aperture distance of the microstructure array can be measured with high precision by the research of Halcon. The algorithm of threshold segmenta-tion, holes filling and opening circle were used in the measurement system design, and the sub-pixel edge extraction and least squares fitting circle method were also usd. The high precision white light interferometer and the designed detection system respectively measure the same microstructure array, by comparing the da-ta, it is verified that the measurement system meets the design requirements.
