Unidirectional laser oblique illumination (ULOI): A comparison with partial dark field illumination (PDFI) in the optical microscopy of metals

Some metallographic observations of the surface of polycrystalline specimens in an optical microscope illuminated with a HeNe laser beam, at oblique incidence, are compared with observations with white light also at oblique incidence. It is shown that similar effects are obtained in both cases; howe...
