DEVELOPMENT OF A HIGH-SPEED LOW JITTER SCANNING TECHNIQUE FOR APPLICATION TO RADAR SIMULATION.
Abstract
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 1p/mm 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.
