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.
Structured light plethysmography Structured Light Plethysmography (SLP) technology utilises pc gaming/movie techniques to scan a patient with visible light, capture an image, measure movement in the image and produce accurate, real-time data on changes in respiration. A checkerboard pattern of light is projected from a light projector onto the chest of an individual. Movements of the grid are viewed by two digital cameras, digitalised, and processed to form a 3D model and can be interrogated to assess lung function. The system has been tested on over 70 adults (data presented at clinical meetings). SLP is simple to use, accurate and cost effective, is self-calibrating and does not require the use of plastic consumables, reducing cost, risk of cross infection and the device's carbon footprint. In conjunction with the Cambridge Veterinary School, proof of concept studies have indicated that the device is sensitive enough to noninvasively pick up respiratory movements in domestic animals (cats and dogs).
