Engineering a gigapixel monocentric multiscale camera

Multiscale designs greatly simplify the large-scale optics needed to realize the resolution of a large aperture. Unlike most monolithic lens systems, multiscale cameras have interdependencies between the optics at various scales. To realize a successful multiscale design, the relationships between microcamera scale and overall camera scale parameters must be understood. Starting with a specification of the multiscale camera, we present a simplified model that allows paraxial optical quantities to be estimated. Based on these quantities, a monocentric objective and a microcamera can be designed. An example of a practical design using spherical glass optics is presented.
