Abstract
A fingerprint identification apparatus including a light-transmitting device, an image-capture device disposed opposite to the light-transmitting device, and a collimator disposed between the light-transmitting device and the image-capture device is provided. The collimator includes a plurality of light-shielding layers and a plurality of light-transmitting layers that are alternately stacked. Each of the light-shielding layers has a plurality of openings respectively corresponding to a plurality of pixel regions of the image-capture device. Openings of the plurality of light-shielding layers corresponding to one pixel region are arranged along an oblique direction. The oblique direction and a normal direction of a pressing surface of the light-transmitting device have an included angle θ, and 0°<θ<90°.
