Abstract

In the accompanying drawing, a light gate array 12 is illuminated by an aDerture fluorescent lamp 14. The lamp emits most of its actinic radiation through a relatively narrow aperture 20, where & is typically around 5 to 10 degrees about the light beam direction shown by arrow heads 18; the aperture is always less than 20 degrees. Efficient coupling of the light takes place by having the lamp 14 in very close proximity to the light gate array 12, which may be a linear system, a quasi-linear system, or a staggered array of gates.
