Retina image formation enhancement through active nanoparticle-based photoreceptors

A vision system, comprising:

• an image capture system, comprising:
• an image capture device having an image sensing element configured to receive light from an object and generate object-shape signals commensurate with shape of the object,
• a processor executing software maintained on a non-transitory memory and configured to:
• receive the object-shape signals,
• perform edge detection on the object-shape signals,
• generate edge-detected signals representing edges of the object, and
• one or more light-generating devices, each configured to generate pulses of light at a predetermined transmitted wavelength;
• and
• a plurality of artificial photoreceptors (APRs), each comprising:
• a nano-dielectric core,
• a plurality of optical dipoles each optical dipole attached to the surface of the nano-dielectric core, and each optical dipole comprising:
• a first nano-particle configured to generate a positive voltage when receiving a light having a predetermined wavelength, and
• a second nano-particle configured to generate a negative voltage when receiving a light having the predetermined wavelength,
• wherein one or more dielectric coatings applied to each of the nano-dielectric cores and each of the plurality of optical dipoles,
• wherein the processor controls the one or more light generating devices based on the edge-detected signals such that:
• i) a plurality of a first set of the first and second nano-particles of the plurality of optical dipoles cancel each other's voltages such that the plurality of APRs only generate voltages at locations corresponding to the edge-detected signals;
• or ii) a plurality of a second set of the first and second nano-particles of the plurality of optical dipoles generate positive and negative voltages to sequentially generate responses for biological receptors.
