A breadboard model scanner was modified to incorporate a six-lens, rotating optical scanning system and sync. pulse generation circuitry. The modified scanner consists of a laser light source, a beam expander, a beam normalizer, a six-lens, air-bearing, rotating optical scanning system, a holder for a 2-inch-wide transparency, a light collector, a photo-multiplier assembly, a video amplifier, sync. pulse generation circuits and a high voltage power supply. Using a laser source to generate a small optical spot, a capability of distinguishing 200 1pmm and 30 shades of grey from light to dark was demonstrated while maintaining the jitter along the sweep and perpendicular to the direction of sweep of one-fourth of a spot diameter.
