Abstract
This paper introduces alternative to existing, glass scale quality parameters measurement method based on optical focusing, which is used in optical disk data reading. Using relatively simple data processing algorithms we were able to detect possible errors and position of the errors on the glass scale. Research showed that measurement method could be used for quality parameters evaluation, but requires usage of the laser pick up heads with known parameters
