Abstract
An invention is disclosed in which a light source provides light beams of different wavelengths which are projected to an object to form images thereon at substantially the same degree of focus and magnification. The reflected images are received by two photosensors, each responsive to one of the wavelengths, which produce signals indicative of surface features of the object. Increased resolution of small surface features is obtained through the similarities of focus and magnification.
