1. An imaging device, comprising: an imager including a sensor and at least one optical element to focus light on the sensor; a multiplexing assembly that divides a pupil area of the imager into a plurality of continuous sub-pupil regions that each direct collected light to form an image on the focal plane of the imager that fills the focal plane of the imager and defines an image channel; wherein the light from each image channel is of a same spectrum and the multiplexing assembly simultaneously directs the light from each image channel onto the focal plane of the imager such that the image channels overlap on the focal plane of the imager and each pixel on the focal plane simultaneously views multiple object points or the same object point from multiple perspectives.
