Abstract

An apparatus for imaging an object comprises a plurality of shutter elements (601, 606, 614) and a sensor (603, 608, 612), each shutter element (601, 606, 614) being operable to control (602, 609, 613) passage of light from a separate spatial location on the object to be imaged, wherein the incident light from the shutters (601, 606, 614) simultaneously illuminates a common area on a sensor (603, 608, 612) surface and wherein the incident light from the different shutters (601, 606, 614) is still individually discernible due to shutter control (602, 609, 613).
