Abstract

Embodiments of the invention relate to a method and apparatus for imaging. Specific embodiments can incorporate an imaging module having at least one first imager, where each first imager images a corresponding at least one first portion of a θ° field of view about a reference point, such that the at least one first imager images the θ° field of view. In a specific embodiment θ is at least 90°. The imaging module can also incorporate at least one second imager, where each second imager images a corresponding at least one second portion of the θ° field of view about the reference point, and one or more of the at least one first imager has a different magnification than one or more of the at least one second imager. Embodiments can allow imaging of a θ° field of view about a reference point with imagers having at least two different magnifications.
