HOLOGRAPHIC LIGHT FIELD IMAGING DEVICE AND METHOD OF USING THE SAME

摘要

A holographic light field imaging device and method of using the same. The holographic light field imaging device may optically compress the light field into a lower-dimensional, coded representation for algorithmic reconstruction by transforming the light field in a known, calculable way. The resulting wavefront may be optically compressed before capture, wherein the compression may later be reversed via software algorithm, recovering a representation of the original light field.

1. A holographic light field imaging device, comprising:
at least one compression array; at least one image sensor; wherein said at least one compression array comprises one or more encoding masks and a first surface; wherein light striking said first surface creates an incident light field; wherein said incident light field is passed through said one or more encoding masks, such that said incident light field is reduced from a four-dimension representation to a two-dimension representation, such that a dimensionally-reduced light field is created; wherein said two-dimension representation of said dimensionally-reduced light field is recorded by said image sensor, such that one or more reduced two-dimensional images are created; and wherein said one or more reduced two-dimensional images are processed by a computing device, which comprises a reconstruction algorithm that inverts said one or more reduced two-dimensional images to reconstruct said incident light field.
