摘要
The present invention is a camera with video-rate acquisition and processing for medical imaging applications. In particular, the invention is used to determine the health of a body area by quantitatively measuring blood oxygen levels and melanin content from a real-time video image of a body segment. In certain embodiments, a camera comprises an objective lens; a filter tray located at an aperture stop of the objective lens, wherein the filter tray comprises a plurality of elements, each element passes a spectral band of light; a micro-lens array located at an exit pupil of the objective lens comprising a plurality of micro lenses to form an image plane, wherein the objective lens produces a focused image at the image plane; and a focal plane array comprising a plurality of sensors, wherein each sensor receives light from at least one micro-lens of the micro-lens array.
