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.
Optical table An optical table is a vibration control platform that is used to support systems used for laser- and optics-related experiments, engineering and manufacturing. The surfaces of these tables are designed to be very rigid with minimum deflection so that the alignment of optical elements remains stable over time. Many optical systems require that vibration of optical elements be kept small. As a result, optical tables are typically very heavy and incorporate vibration isolation and damping features in their structure. Many use pneumatic isolators that act as mechanical low-pass filters, reducing the ability of vibrations in the floor to cause vibrations in the tabletop.
