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

Abstract: 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.
