DYNAMICALLY FOCUSABLE MULTISPECTRAL LIGHT FIELD IMAGING

摘要

A flexible, multispectral, light field imaging system comprising holographically-formed polymer dispersed liquid crystal (H-PDLC) stacks in a plenoptic camera architecture may capture multispectral light field data from a scene. Through manipulation of this multispectral light field data, digitally refocused spectral images may be created at different, selectable focal depths, with a single exposure.

主权项

1. A method comprising:
directing optical signals, via an imaging lens, to a dynamic filter, wherein the optical signals are representative of an object; filtering, by dynamic filter, the directed signals; directing filtered signals to an array of lenses; directing signals from each lens of the array of lenses to an image sensor, wherein the image sensor comprises a plurality of detector elements; and reconstructing signals detected by detector elements of the plurality of detector elements to generate a visual representation of the object, wherein reconstructing the signals comprises dynamically focusing the visual representation at a selectable focal point.
