title: The production of apparent image bifurcation.
abstract: It is well known that x-ray focal spots with split-intensity distributions can produce radiographs exhibiting image bifurcations. The authors observed such bifurcations in optical analogue images which were produced with both split- and uniform-intesity focal spots. The bifurcations observed with the split focal spot were real, while those observed with the uniform focal spot were not observed in photometer scans of the object. The authors explain these bifurcations by a consideration of the response function of the eye.
