Here I’ll cover how sensors can collect readings from an environment and represent those readings in a practical way.  The most common field scanning devices are flat bed scanners and cameras.  These devices either have a line of sensors or an array of them to take readings quickly.  Flat bed scanners typically have a line of sensors that detect light and color.  As the sensors move along the surface of an object, typically paper, they buffer the readings into memory.  … Continue reading Field Scanning
