The present invention provides a plenoptic camera which captures information about the direction distribution of light rays entering the camera. This plenoptic camera includes a main lens, which receives light from objects in an object field, and directs the received light onto an image plane of the camera. It also includes a photodetector array at the image plane of the camera, which captures the received light to produce an image. Unlike a conventional camera, the plenoptic camera includes an array of optical elements located between the object field and the main lens. Each optical element in this array receives light from the object field from a different angle than the other optical elements in the array, and directs a different view of the object field into the main lens. Thus, the photodetector array receives a different view of the object field from each optical element in the array.
