A method and apparatus for determining the dimension, location, orientation, presence, or identity of at least a portion of an object. An object or a portion thereof is imaged onto an end of an at least partially non-coherent optical fiber bundle whereby the image incident on said end of said fiber bundle is transmitted to the other end thereof. The image is transferred from the other end of the non-coherent optical fiber bundle onto a photodetector comprising a plurality of discrete photodetector elements. The output of the photodetector elements is utilized to determine a characteristic of the lighted or unlighted portion at the other end of the non-coherent fiber bundle, and the characteristic is used to determine a dimension, location, orientation, presence, or identity of the object or portion thereof.
