Diffraction technique for the inspection of injection moulded optical disc
Control of the micro-pit or groove geometry is of major importance in the injection moulded optical disk (CD, CDR and DVD) and also the mastering of the disc. Basically, the optical disk geometry can be described in terms of the pit (groove) depth, full width at half maximum (FWHM) and the wall angl...
