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.
Goniophotometer A Goniophotometer is a device used for measurement of the light emitted from an object at different angles. The use of goniophotometers has been increasing in recent years with the introduction of LED-light sources, which are mostly directed light sources, where the spatial distribution of light is not homogeneous. If a light source is homogeneous in its distribution of light, it is called a Lambertian source. Due to strict regulations, the spatial distribution of light is of high importance to automotive lighting and its design.
