Vignetted planar spatial light-field sensor and spatial sampling designs for far-field lensless synthetic imaging via signal processing image formation

摘要

Methods of implementing light field sensors for lensless synthetic imaging is provided. Relatively tall and short structures are fabricated, wherein the short structures comprise light sensing capabilities. The tall structures and short structures are arranged in an array to create an array of vignetted light sensors that partition an incoming light field into a plurality of vignetted light fields, each uniquely associated with a particular light sensor. Each light sensor generates a measurable electrical quantity responsive to the associated vignetted light field, and the collective measurable electrical quantities are responsive to incoming light field. The short structures can comprise photodiodes, LEDs, or OLEDs, and the resulting light field sensor can respond to color. Tall structures can comprise electronic components, LEDs, OLEDS, or OLETs. In an example implementation, tall structures in the array are light-emitting and act as a light-emitting visual display which further comprises an array of vignetted light sensors.

1. A method for implementing light field sensor for use in lensless synthetic imaging, the method comprising:
Fabricating relatively tall structures and short structures, wherein the short structures comprise light sensing capabilities, and wherein the tall structures and short structures are arranged in an array to create an array comprising a plurality of vignetted light sensors, and Receiving an incoming light field, Partitioning the incoming light field with the tall structures to created a plurality of vignetted light fields, each vignetted light field uniquely associated with a particular vignetted light sensor from the plurality of vignetted light sensors, Receiving each vignetted light field at the associated each vignetted light sensor, and Generating, at each vignetted light sensor, a measurable electrical quantity responsive to the associated vignetted light field, Wherein the vignetted light sensors comprising a vignette depth resulting from the difference in height between the tall structures and short light-sensing structures, and Wherein the collection of the measurable electrical quantities from each of the vignetted light sensors is responsive to the received incoming light field, the plurality of vignetted light sensors thereby acting as light field sensor.
