Contact-type image sensor for identifying hologram image

The invention discloses a contact-type image sensor for identifying information images of a hologram, belonging to the technical field of electronic information. The contact-type image sensor is provided with a frame, a glass plate, a circuit board, photo-electric conversion chips, lenses and a light source. The invention is characterized in that the circuit board is provided with at least two columns of photo-electric conversion chips; one column of lenses are correspondingly installed on the upper parts of each column of photo-electric conversion chips; and different angles are formed between each column of lenses and the glass plate to provide multiple reading angles. In the invention, the hologram can be read at different angles through the set multiple columns of photo-electric conversion chips and the set multiple columns of lenses with different angles; and the read image can be regulated to be converged to focus positions of different lenses through setting a refractive plate with different thicknesse
