Barcode Scanner Microscope Analyzes Complex Medical Problems
In barcode scanners, a laser beam bounces off a spinning polygon mirror, allowing it to scan across a sample very quickly. A barcode scanner registers a sequence of patterns to identify a product. A polygon mirror usually has around 10 mirror facets. The ANU researchers used a more powerful laser beam as the light source and up to 36 mirror facets to scan the laser beam across the biological sample in a few thousandths of a second.
