Barcode reader exploits holographic technology By incorporating holographic-lens technology, the StrataScan barcode reader produces multiple scan lines at different layers for a depth of field of up to 42 in. Combined with a high-speed processor, the reader can detect labels at speeds to 300 ft/min. It can decode virtually all standard barcodes. A single holographic disk, the only moving part, replaces the focusing lens, light-collection lens, and rotating mirror of a stan-
dard laser scanner. Pricing starts at $8000. Rockwell Automation/Allen-Bradley, 10701 Hampshire Ave. South, Bloomington, MN 55438; (800) 223-5354; Fax: (800) 500-0329.
