Abstract

An imaging device for use with an endoscope, the imaging device comprising: a lens arrangement operable to receive light from a scene captured by the endoscope and to form an image of the scene using the received light; an image sensor operable to capture the image of the scene formed by the lens arrangement; a birefringent device positioned along an optical path between the endoscope and the image sensor, wherein the birefringent device comprises birefringent material arranged in a plurality of concentric rings, and wherein the birefringent material of each of the concentric rings is configured such that the polarisation directions of an ordinary ray and an extraordinary ray of light from the scene which travels through the birefringent material are different for at least two of the plurality of concentric rings; and an image processor operable to process the captured image to generate an output image.
