Abstract
A system for projecting a spot of radiant energy includes a lamp for projecting a light spot onto a surface and includes means for providing a selection of differently sized spots. Drive means moves the light spot relative to the surface and is capable of moving the light spot at a maximum given velocity which is the same for all of the differently sized spots. Velocity output means produces a velocity signal representing the velocity of the spot and a normalized velocity signal is produced by dividing the volocity signal by the maximum given velocity. Each differently sized spot is assigned a different lamp command voltage signal and a selected one of the lamp command voltage signals is multiplied by the normalized velocity signal to produce a resultant lamp command voltage signal which energizes the lamp.
