Abstract
A check Sorter-Imager-Processor with two (or more) imaging sites, each lit by a beam through a fibre-optic array--with a lens focusing the beam on each array such that a shift in lens-focus reduces output light from the array,--the two sites being thus 'matched' in light-intensity by merely focus-adjusting these lenses.
