摘要： An optical fingerprint imaging system and an optical assembly are provided. The optical fingerprint imaging system includes: a sensor including a substrate and a photosensitive layer, wherein the substrate has a first surface and a second surface which is opposite to and lower than the first surface, and the photosensitive layer is in contact with the first surface of the substrate; a light source disposed at a position lower than the first surface and higher than the second surface, and light emitted from the light source is adapted to be guided by the substrate of the sensor to the first surface of the substrate; and a mounting element adapted to mount the light source at a fixed position. Accordingly, the optical fingerprint imaging system has high light use efficiency and stable light source.
