Abstract
An image sensor device includes two or more image sensor arrays (or two or more regions of an image sensor array) and a low-power processor in a same package for capturing two or more images of an object, such as an eye of a user, using light in two or more wavelength bands, such as visible band, near-infrared band, and short-wave infrared band. The image sensor device includes one or more lens assemblies and/or a beam splitter for forming an image of the object on each of the two or more image sensor arrays. The image sensor device also includes one or more filters configured to select light from multiple wavelength bands for imaging by the respective image sensor arrays.
