    摘要： Methods and Apparatuses are provided for a thin high contrast optical acquisition system for fingerprint recognition. In one embodiment, a method of capturing images of a fingerprint may include emitting light from a set of light sources to generate a scattered light from the fingerprint, determining a set of sensor arrays located between an inner boundary and an outer boundary from the set of light sources based on thickness and refractive index of one or more panels between the set of light sources and the fingerprint, activating the set of sensor arrays to capture the scattered light from the fingerprint, and processing the scattered light captured by the set of sensor arrays in parallel to generate a topography of the fingerprint.

    摘要： An apparatus and method for acquiring an image of a patterned object such as a fingerprint including a light refracting device, a focusing lens, and a light source. The light refracting device can, for example, be a prism and includes an imaging surface, a light receiving surface and a viewing surface. Incident light from the light source is projected through the light receiving surface and reflected off a surface other than the imaging surface. This reflected light is then projected onto the imaging surface to create an image of the patterned object from substantially all scattered light through the viewing surface. The lens is placed adjacent to the viewing surface to focus the light on an image sensor. The apparatus is configured to reduce or substantially eliminate trapezoidal distortion and improve overall image sharpness in an image of an object created by the apparatus.

    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.
