Opto-electric scanner uses light transmitter whose beam is controlled so that its angle increases and photoreceptor which detects objects in area being scanned, digital camera detecting orientation of zone protected by scanner

摘要

The opto-electric scanner (1) uses a light transmitter whose beam (2) is controlled, e.g. by an oscillating mirror, so that its angle increases, shortening the time required for scanning, and a photoreceptor which detects light reflected from objects (5) in the area being scanned. In addition, a digital camera (30) detects the orientation of the zone (3) protected by the scanner.
