Abstract
An apparatus for producing ring patterns from electron diffraction spot patterns, which comprises in combination a transparent disc rotatably mounted, rotating means for said disc, a light source beneath said disc, and photographic means above said disc. The invention also embodies a method for producing ring pattern negatives from an electron diffraction spot pattern negative by photographing the spot pattern negative while it revolves at a speed of at least about 0.5 rps.
Claims1
An apparatus for producing ring patterns from an electron diffraction spot pattern which comprises in combination, a frame supporting a rotatably mounted transparent disc having a center hole for centering an electron diffraction spot pattern negative on said disc, rim drive means for said disc, a light source mounted on said frame beneath said disc and directed upwardly at said disc, and photographic means mounted on said frame above said disc to photograph the ring pattern generated when said mounted spot pattern negative is revolved.
