Abstract
Fiber optic displacement/position measuring apparatus having increased working distance and measuring range capability is provided by combining an optical extending sensing head in fixed relationship with the common end of a bifurcated fiber optic bundle. The sensing head includes a lens system which is operative to focus the image of the end face of the fiber optic bundle onto the surface of an object whose displacement is to be determined and to refocus that image back onto the end in an upright relationship.
