Contact-type image sensor for holographic image identification

The utility model discloses a contact-type image sensor for the holographic image identification, which belongs to the technical field of electronic information. The contact-type image sensor is provided with a frame, board glass, a circuit board, photoelectric conversion chips, lenses and a light source. The utility model is characterized in that at least two rows of photoelectric conversion chips are arranged on the circuit board, a row of lenses are correspondingly arranged above each row of photoelectric conversion chips, and each row of lenses have different angles with the board glass for providing various reading angles. The utility model can help users to read holographic images in different angles through the arrangement of various rows of photoelectric conversion chips and various rows of lenses in different angles, the read images can be regulated to be converged in focus positions of different lenses through the arrangement of dioptric boards with different thicknesses under the lens, and the clea
