Abstract

We discuss the problem of performing nonintrusive measurements to determine the geometric parameters of poorly accessible objects. An optical system with a compact prism–lens objective was developed for simultaneously imaging a target object from two different points of view on a single detector array. A prototype of the proposed system was also constructed. The resulting optical system was experimentally confirmed to have high image quality. The shape of the test surface can be stereoscopically reconstructed via digital processing of the images, including high-accuracy determination of the geometric parameters of the surface. The results described here may have applications in machine vision, nondestructive testing, and other areas.
