Various aspects of the present disclosure are directed toward optics and imaging. As may be implemented with one or more embodiments, an apparatus includes one or more phase masks that operate with an objective lens and a microlens array to alter a phase characteristic of light travelling in a path from a specimen, through the objective lens and microlens array and to a photosensor array. Using this approach, the specimen can be imaged with spatial resolution characteristics provided via the altered phase characteristic, which can facilitate construction of an image with enhanced resolution.

Light-field microscopy with phase masking

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.
