摘要： Fingerprint sensors include a plurality of optical sensor elements, a collimator filter disposed above the plurality of optical sensor elements, and a display disposed above the collimator filter, wherein the display is a fingerprint imaging light source. The collimator filter has a plurality of apertures, and the plurality of optical sensor elements is configured to receive light transmitted through one aperture of the plurality of apertures.

摘要： Systems and methods for optical imaging are disclosed. The optical fingerprint sensor includes an image sensor array; a collimator filter layer disposed above the image sensor array, the collimator filter layer having an array of apertures; and an illumination layer disposed above the collimator filter layer. The collimator filter layer filters reflected light such that only certain of the reflected light beams reach optical sensing elements in the image sensor array. Employing the collimator filter layer prevents blurring while allowing for a lower-profile image sensor.
