An imager array may be provided as part of an imaging system. The imager array may include a plurality of sensor arrays (e.g., also referred to as lenslets or optical elements). Each sensor array may include a plurality of sensors (e.g., pixels) associated with a lens. The sensor arrays may be oriented, for example, substantially in a plane facing the same direction and configured to detect images from the same scene (e.g., target area). Such images may be processed in accordance with various techniques to provide images of electromagnetic radiation. The sensor arrays may include filters or lens coatings to selectively detect desired ranges of electromagnetic radiation. Such arrangements of sensor arrays in an imager array may be used to advantageous effect in a variety of different applications.
