Abstract
A biometric imaging device configured to be arranged under an at least partially transparent display panel and configured to capture an image of an object located on an opposite side of the transparent display panel. The biometric imaging device comprises an image sensor comprising a photodetector pixel array; a transparent substrate covering the photodetector pixel array; a first set of microlenses configured to redirect light through the transparent substrate and onto a subarray of pixels in the photodetector pixel array. The lenses in the first set have a first focal length. A second set of microlenses configured to redirect light through the transparent substrate and onto a subarray of pixels in the photodetector pixel array. The lenses in the second set of microlenses have a second focal length which is different from the first focal length.
