摘要:
A fingerprint identification apparatus, including a light path adjustment element, an optical filter layer, and an image sensor, is provided. The light path adjustment element is disposed on a transmission path of an image beam from a fingerprint of a user. The optical filter layer is disposed on a transmission path of the image beam from the light path adjustment element. The optical filter layer has openings. An inclined image beam in the image beam is obliquely incident to the light path adjustment element. The light path adjustment element adjusts a light path of the inclined image beam to be transmitted to the openings along a normal direction. The image sensor is disposed on a transmission path of the image beam from the optical filter layer. The image sensor has pixels. Positions of the pixels respectively correspond to positions of the openings.
