LEDs are often used in machine vision systems, which require bright and even illumination. Machine vision is a technology in which hardware and software work together to help machines inspect, process and guide and act in response.
Barcode scanners are an example of machine vision application – they read barcodes, sending the data to a computer for processing. Product barcodes allow workers to quickly scan a product for price and information. Barcodes allow pricing and product information to be centrally updated, eliminating the need for individual product pricing updates.
