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.

Abstract: Methods use a tunable notch filter for constructing a spectral map of electromagnetic radiation in a selected spectral band that is incident on a notch filter for a plurality of time periods. Electromagnetic radiation is passed by an electronically tuned notch filter to a detector array for the plurality of selected time periods, and the detector response is determined. For at least a first selected time period the notch filter is tuned to selectively attenuate the passing of one or more selected sub-bands of electromagnetic radiation in the selected spectral band. Information about the selectively attenuated radiation is determined and used along with information about the radiation passed to the detector array for each time period to construct a spectral map. Electronically tunable notch filters may be made with metamaterials such as patterned graphene.

Abstract: Display devices can be used to provide display functionality in dynamic autostereoscopic displays. One or more display devices are coupled to one or more appropriate computing devices. These computing devices control delivery of autostereoscopic image data to the display devices. A lens array coupled to the display devices, e.g., directly or through some light delivery device, provides appropriate conditioning of the autostereoscopic image data so that users can view dynamic autostereoscopic images.
