This course provides attendees with a basic working knowledge of optical and laser scanning devices and scanning system design. The course covers: scan patterns; pre-objective and post-objective system configurations; reflective, holographic and transmissive scanners; polygonal, galvanometric, resonant and acousto-optical scanners; their advantages and disadvantages.
The course illustrates:
• Cross- and along-scan errors and how to minimize their effects.
• Polygonal facet errors and how to reduce their effects on image quality.
• Stationary ghost images in the image format and how to eliminate them.
You will become at ease with how one designs an optical scanning system for many varied applications.
The course covers the principles of optical scanning, beam characteristics, optical configurations, scanner types, mechanical aspects, image quality, and design procedures. It describes and compares reflective, refractive and diffractive scanning devices, and illustrates the applications of scanning devices, input (readers) and output (recorders) scanners.
