Abstract
Images are detected in a manner that addresses various challenges as discussed herein. As may be consistent with one or more embodiments, aspects are directed to an apparatus having sets of photosensors that detect light rays received at different angles from a specimen via a microlens array, with the light rays detected by each set of photosensors representing an aliased view of the specimen. An output indicative of aliased views of the specimen is provided. Certain embodiments further include a logic circuit that processes the output and generates a deconvolved volume image by combining aliased views of the specimen as detected by the photosensors.
