Example Embodiment
[0026] The glass grinding amount is reflected by the change of the optical path difference in the grinding amount monitoring device, and the change of the optical path difference is reflected by the offset of the fringe. By monitoring the offset of the fringe, the purpose of online monitoring of the grinding can be achieved. To realize the invention, the following content must be included:
[0027] 1. Provided is an on-line monitoring device for grinding amount of white light interference workpieces (hereinafter referred to as grinding amount monitoring device) that can be used for ring polishers. The device can adjust the contrast of white light interference fringes and eliminate the influence of dispersion on white light interference.
[0028] 2. To provide an online monitoring method for grinding amount based on a grinding amount monitoring device, which includes two steps:
[0029] a. A monochromatic LED with a known wavelength is used to calibrate the grinding amount monitor...
