专利汇可以提供Photo detector专利检索,专利查询,专利分析的服务。并且PURPOSE: To miniaturize an element by reading color information in a short time with excellent resolution without using a lens system, by providing one-way arrays of multi-column photoelectric converter onto a substrate which has an optical fiber column at one part.
CONSTITUTION: At the part surrounded by stripe electrode 19 and three upper metal electrodes 21, 22 and 23, three columns of photo-diode one-way arrays are formed. In this case, semiconductor film 20 is used in common and its lateral resistance is high enough not to cause crosstalk among photo-diode one-way arrays. Light emitted from light source 24 is scattered by color original 25, color-separated by three color-filters 16, 17 and 18 and made to strike corresponding photo-diode one-way arrays, where they are read after independent photoelectric conversion.
