| Abstract: | A novel method of measuring eyeglass's focus is proposed,which is based on DSP. The method applies high-resolution linear CCD to get image signal, its signal sampling, signal processing, calculation and controlling stepping motor to focalize are carried out by a Digital System Processing (DSP) system. Thereby we get optical parameters of the eyeglass. |

| Keywords: | lensmeter linear CCD digital system processing stepping motor |
