Abstract
A light field relay has an array of microlenses, an array of transducers, and an array of output optics. Microlenses focus one or more than one selected portions of an incident light field to separate corresponding transducers. Each corresponding transducer receives and transduces a single portion of focused light and emits the transduced light. Corresponding different output optics substantially collimate the transduced light and emit the substantially collimated light as an emitted light field. The light field relay may collect infrared light in one or more selected portions of an incident light field, transduce the infrared light to visible light, substantially collimate the transduced visible light, and emit a visible light field.
