optical resolution

The built-in resolution of a scanning device. Contrast with "interpolated resolution" or "digital resolution," which enhances an image by software. Both resolutions are given as dots per inch (dpi), thus a 2,400 dpi scanner can be the true resolution of the machine or a computed resolution. See optical zoom, interpolated resolution and scanner.
