ABSTRACT
This entry explains a computational imaging technique called wavefront coding that extends the depth of field of an incoherent imaging system. In accordance with one of the main tenets of computational imaging, this approach involves distributing the process of image formation between the optical and digital electronic subsystems of a modern imager. The resulting hybrid electro-optic architecture enables objects within a larger range of distances to be in focus simultaneously than would be possible with a traditional imaging system. This entry also discusses applications of this technique to an assortment of imaging tasks and a brief overview of some of the trade-offs involved in this approach.
