A vacuum tube containing a photosensitive area, or target, and an electron gun to
read the signal from the target. The silicon target consists of a two-dimensional
array of Si-photodiodes having a common
cathode and isolated anodes.
Irradiation of the target causes the production of electron-hole pairs which, by recombination,
leads to a depletion of the surface charge.
