Optical signal receiver comprising a multi-tap pixel

A network data transceiver comprising:

• a plurality of pixels, each pixel comprising:
• a photodetector;
• and
• a plurality of taps, each tap comprising:
• a floating diffusion capacitor;
• a transfer gate for controlling charge flow between the photodetector and the floating diffusion capacitor;
• and
• readout circuitry;
• and
• a controller comprising instructions executable for controlling a pixel in the plurality of pixels to:
• in a first period of time:
• perform a first integration on the photodetector;
• readout charge stored on the floating diffusion capacitor of a first tap in the plurality of taps using the readout circuitry of the first tap;
• in a second period of time;
• perform a second integration on the photodetector;
• readout charge stored on the floating diffusion capacitor of a second tap in the plurality of taps using the readout circuitry of the second tap.

An optical glass storage reading system comprising:

• a repositioning system for repositioning the optical glass storage reading system;
• and
• a read head comprising;
• a light source for illuminating the optical glass storage system;
• a microlens array for focusing light from the light source onto a voxel array of the optical glass storage system;
• a photosensor array comprising:
• a plurality of pixels for receiving light from the optical glass storage system, each pixel comprising:
• a photodetector;
• and
• a plurality of taps, each tap comprising:
• a floating diffusion capacitor;
• a transfer gate for controlling charge flow between the photodetector and the floating diffusion capacitor;
• and
• readout circuitry;
• and
• a controller comprising instructions executable for controlling each pixel to:
• in a first period of time:
• accumulate a first charge on the photodetector;
• and
• transfer the accumulated first charge to the floating diffusion capacitor of a first tap in the plurality of taps;
• in a second period of time;
• accumulate a second charge on the photodetector;
• and
• transfer the accumulated second charge to the floating diffusion capacitor of a second tap in the plurality of taps;
• and
• in a third period of time;
• readout the first and second charges stored on the floating diffusion capacitors of the first and second taps;
• reset the floating diffusion capacitors of the first and second taps;
• and
• read the reset floating diffusion capacitors of the first and second taps.
