Resolution

The resolution of the scanner refers to the ability of an imaging system to measure the angular separation between two objects (or object features) that are close together. The resolution is a limitation of the scanner in the x-y dimensions. For example if a target has embossed lettering, and the font size is smaller than the resolution of the scanner then the text will not be legible in the scanned image, regardless of the height (z-depth) of the lettering.

The resolution is determined by three major factors: the laser stripe width, the lens focal length, and the CCD resolution. The resolution is dependent on the target distance and generally gets worse with increasing range.
