Abstract: RD-123??     NON-CONTACT MEASUREMENT OF SURFACE PROFILE     Abstract of the Disclosure A parallax method of wavelength labeling is based on optical triangulation.  A complementary color pattern projected onto the surface is characterized by a continuous variation of the power ratio of two wavelength bands, and the profile can be measured at all points in the field of view.  Shifts of the wavelength bands on separate detector arrays correspond to profile deviations.  A signal processor calculates a normalized signal that is independent of surface reflectivity and roughness variations; the phase shift of this signal yields depth data from which the surface profile can be mapped.

Abstract: Abstract of the Disclosure This apparatus forms and displays sequentially a plurality of three-dimensional images.  In known apparatus for displaying three-dimensional images no provision is made for comparing the different images.  This problem is solved by projecting a plurality of images.  Frames from a film strip are stroboscopically selected and projected on a moving screen.          The effect may be simply a comparison of two three-dimensional images.  Alternatively, an illusion of motion of a three-dimensional image may be created.  Safety features prevent access to rotating parts and other features protect the strobo-scope from excessive and unnecessary use.  A single three-dimensional image may be selected and continuously projected on the screen.
