Abstract

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.
