1. A contactless biometric data collection device comprising: an image capture device configured to capture images of a subject hand in any of a range of positions and at each of a plurality of different focal distances, each of the images comprising at least a portion of the subject hand, wherein the image capture device comprises: an imaging camera configured to capture the images at a first image resolution level; and an electro-optics arrangement positioned between the hand and the imaging camera, the electro-optics arrangement including a plurality of light modulating elements and polarization sensitive optical elements having an optical path length that changes with different polarization states, so as to provide for capture of the images at each of the plurality of different focal distances; and a control system coupled to the image capture device, the control system being configured to: cause the image capture device to capture the images at each of the plurality of different focal distances, each image having a depth-of-focus that overlaps with a depth-of-focus of images at adjacent focal distances such that redundant image data is captured; register each image with positional data so as to create pixel correspondence between the images and between portions of the hand; and create a composite image from the registered images captured at each of the plurality of different focal distances.
