ABSTRACT:
A cost-effective optical device is used for converting a photo-image into electronic signals with high resolution. The optical device includes a plurality of focusing units for receiving a plurality of sections of the photo-image respectively, and generating a plurality of corresponding focused image sections wherein the focusing units are mounted in specific locations for focusing the plurality of sections of the photo-image through various light paths and at various distance, and the plurality of corresponding focused image sections are magnified with the same ratio, a photoelectric conversion unit for sequentially converting the plurality of corresponding focused image sections into the electronic signals, and a light-reflecting unit mounted between the plurality of focusing units and the photoelectric conversion unit for sequentially transmitting the plurality of corresponding focused image sections to the photoelectric conversion unit.
