摘要： Methods and Apparatuses are provided for a thin high contrast optical acquisition system for fingerprint recognition. In one embodiment, an apparatus for determining validity of a fingerprint includes a light refracting device (light refractor), a light source, a light collecting device, and a controller. The light refracting device can, for example, be a TFT light panel structure or an active matrix organic light emitting diode (AMOLED) panel structure with reverse current measurement and amplification circuitry, and includes an imaging surface and a viewing plane. Incident light from the light source is projected directly or indirectly onto the imaging surface to create an image of the patterned object from the projected light onto the viewing plane. The apparatus is configured to have a thin form factor, which may be flexible or conformable, compared to conventional optical fingerprint acquisition apparatuses.
