Abstract
An optical sensor includes a vortex diffuser bearing for support of the optical elements thereof in a fixed, spaced apart and angular relationship relative to a subjacent surface. The sensors are readily adapted to be fabricated into matrices adapted for high volume scanning of surfaces, as for example to detect irregularities in the coatings thereof. The sensors are also adaptable for use in photogrammetry, microdensitometry, or other applications wherein precise, stable and repeatable positioning is required.
