Abstract
An optical device may include a pinhole array layer having pinhole array apertures therein. The pinhole array layer may have a first side to be directed toward incoming electromagnetic (E/M) radiation, and a second side opposite the first side. The optical device may also include image sensors. Each image sensor may include image sensing pixels adjacent the second side of the pinhole array layer. The optical device may also include mirrors. Each mirror may be associated with a respective image sensor and respective pinhole array aperture defining a camera. Each mirror may reflect incoming E/M radiation passing through the respective pinhole array aperture to the respective image sensor. A respective baffle may be between adjacent cameras.
