The game Scan Command: Jurassic Park was considered unique for its use of which device that consists of a light source, a lens and a light sensor translating optical impulses into electrical ones?
Barcode reader A barcode reader (or barcode scanner) is an electronic device that can read and output printed barcodes to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain "decoder" circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
Lens Controller A Lens Controller is device that controls motorized photographic lens functions such as zoom, focus, and iris or aperture. Lens controllers can be found internally in modern still camera photographic lenses and as a stand-alone unit in machine vision, remote sensing, optoelectronics systems, and security applications.
