The Research of Transparent Material Thickness Detection System Based on CCD
This paper proposes a transparent material thickness detecting system based on CCD sensor, in order to achieve non-contact on-line detection of transparent material thickness parameter. The system utilizes the principle that the displace error is different between the upper and lower surface of the transparent medium, which is simple in structure, high precision in measurement, and more convenient than the measuring solutions before. This design can solve the thickness and size detection problems of optical glass, optical crystal and optical transparent Polymer Material (or optical plastics).The measurement range is 1-10mm, and measuring accuracy is ±0.01mm.
