Abstract
An optical fingerprint recognition system has a finger board. The finger board has a plurality of micro-structures, and a plate face of the finger board is to be in contact with a finger, and the other plate face of the finger board has an image capturing element and at least one light emitting element disposed thereon. The image capturing element and the light emitting element are separated from the finger board for a distance. When the light emitting element emits a light ray towards the finger board, the light ray is guided by the plurality of micro-structures to be uniformly distributed in the finger board, so as to facilitate the image capturing element to capture the light ray applied on the finger, thus improving the recognition rate of the fingerprint.
