摘要： An optical fingerprint identification system includes a cover, a light emitting layer, an optical layer, an image sensor and a base that are sequentially disposed from top to bottom. The cover has a fingerprint contact surface on top. The image sensor has an image surface. The optical layer includes a first array layer and a second array layer, and the first array layer is stacked on top of the second array layer. The first array layer and the second array layer respectively include a plurality of first array lens elements and a plurality of second array lens elements respectively arranged at equal intervals in a first direction. Each of the first array lens elements and a corresponding second array lens element of the second array layer are coaxial along an optical axis and form an imaging unit.
