photocells

The device they sketched on the board that afternoon was an image sensor based on Albert Einstein's photoelectric effect, in which arrays of photocells would emit electrons in amounts proportional to the intensity of incoming light.

Incoming light releases electrons in the CCD's photocells, the pixels.

This site by Zenith Electronics contains information about the development of remote controls for televisions, covering the "first TV remote control, called 'Lazy Bones,' [which] was developed in 1950 by Zenith Electronics Corporation" and "used a cable that ran from the TV set to the viewer," the 1955 "Flashmatic" wireless remote that used photocells, ultrasonic remotes, and today's infrared remote controls.

The 'wires' connecting the photocells to the brain run over all the surface of the retina, so the light rays have to pass through a carpet of massed wires before they hit the photocells.

Corresponding with changes in daily sunlight, solar photocells in the tree canopy trigger low-voltage charges, activating plectrums that pluck wire strings within the body of the sculpture.

Imagine a latter-day Helmholtz presented by an engineer with a digital camera, with its screen of tiny photocells, set up to capture images projected directly on to the surface of the screen.

But now, suppose I tell you that the eye's 'photocells' are pointing backwards, away from the scene being looked at.

One consequence of the photocells pointing backwards is that the wires that carry their data somehow have to pass through the retina and back to the brain.
