Abstract
An optical comparator which provides confronting images of a pair of similar objects being compared, the images having a pronounced 3-D effect when viewed with a single eye. Images of the two objects are projected in separate optical paths and are greatly enlarged, the resultant composite image showing comparable portions of the two objects side-by-side with a sharp dividing line. The two objects are mounted in related alignment on a common holder and, when the holder is moved, the objects are scanned across their faces with the images converging toward or diverging from the dividing line, depending on the direction of motion of the holder.
Claims11
An optical comparator for providing a 3-D image to one eye, comprising:
- a housing;
- a holder movably mounted in said housing and having means for holding a pair of objects to be compared in spaced corresponding alignment;
- a pair of projection lenses spaced from said holder and positioned to project images of the objects in separate optical paths, one optical path including means for inverting and reverting the image;
- separating means positioned to receive the projected images and separate corresponding portions of the images along a common dividing line;
- image forming means for forming a composite of the projected images joined at the common dividing line;
- and said housing having an eye opening positioned for viewing said image forming means.
