Device for optically transmitting and receiving images
A sensor-display device comprises an array of transmit-receive modules, each of which comprises a light transmitter, a light receiver, and a memory bank. A modulation driver connected to the light transmitter drives the light transmitter to transmit light. The light receiver creates electric charges from light received by the light receiver. A memory interface connects the light receiver to the memory bank for shifting the electric charges as data from the light receiver into the memory bank, and the memory interface shifts the data as electric charges from the memory bank to the modulation driver to drive the light emitter to transmit light based on the electric charges.
1. A device for optically transmitting and receiving images, comprising:
an array comprising a plurality of transmit-receive modules, wherein each of the transmit-receive modules in the array comprises a light transmitter, a modulation driver connected to the light transmitter for driving the light transmitter, a light receiver that creates electric charges from light received by the light receiver, a memory bank, and a memory interface connecting the light receiver to the memory bank for shifting the electric charges as data from the light receiver into the memory bank and for shifting the data as electric charges from the memory bank to the modulation driver to drive the light emitter to transmit light based on the electric charges:
wherein the array comprises an ordered arrangement of multiple rows of the transmit-receive modules and multiple columns of the transmit-receive modules;
wherein each of the light transmitters in the array is oriented to transmit light in the same direction as the other light transmitters in the array, whereby such light transmitted by each light transmitter is a pixel of a transmitted image that is a composite of all the light transmitted by all the light transmitters in the array; and
wherein each of the light receivers in the array is oriented to receive light from the same direction as the other light receivers in the array, whereby light received by each light receiver is a pixel of a received image that is a composite of all the light received by all the light receivers in the array.
2. The device of claim 1 , wherein the memory bank includes a shift register.
3. The device of claim 1 , wherein each of the transmit-receive modules in the array are small enough and in close enough proximity with each other to: (i) transmit light as a pixel of a transmitted image, whereby a composite of the pixels of light transmitted by the array of the transmit-receive modules comprise the transmitted image in sufficient resolution for operating a neural network, and (ii) receive light as a pixel of an incident image, whereby a composite of the pixels of light received by the array of transmit-receive modules comprises the incident image in sufficient resolution for operating a neural network.
4. The device of claim 1 , wherein the light receivers in the array are oriented to receive light from the direction in which the light transmitters in the array transmit light.
5. The device of claim 1 , including a pooling chain connected to the memory banks of the respective transmit-receive modules in the array by which data from multiple transmit-receive modules in the array are readable together and by which data is writable into multiple transmit-receive modules in the array together.
6. A device for optically transmitting and receiving images, comprising:
an array of transmit-receive modules, wherein:
(i) each of the transmit-receive modules in the array comprises a light transmitter, a modulation driver connected to the light transmitter for driving the light transmitter, a light receiver that creates electric charges from light received by the light receiver, a memory bank, and a memory interface connecting the light receiver to the memory bank for shifting the electric charges as data from the light receiver into the memory bank and for shifting the data as electric charges from the memory bank to the modulation driver to drive the light emitter to transmit light based on the electric charges, and
