photocell

There is a built-in photocell on the walnut such as we now have on at least one camera, which automatically adjusts exposure for a wide range of illumination.

5By 1933, the shift from the microscope to the photocell was an attempt to save the scintillation counter by excluding the observer.

As it moves, its potential is varied in accordance with a varying current received over wires from a distant station, where these variations are produced by a photocell which is similarly scanning a picture.

The electron content of each photocell could then be read out, transforming an optical image into a digital one.

That makes good sense, and obviously each photocell has a wire connecting it to a computing device of some kind where images are collated.

THE GREATEST SHOW ON EARTH RICHARD DAWKINS 2009

Karlik replaced the microscope used in the early type of the scintillation counter attached directly to the scintillation screen with a photocell that Blau eventually turned into a photomultiplier. 6
