The Schmitt-Conway biprism is a convex polyhedron with the property of tiling space only aperiodically.
An electron version of the Fresnel biprism is used in electron holography, an imaging technique that photographically records the electron interference pattern of an object.
The two identical beams from the biprism cross in the crystal with a delay that varies in the horizontal direction, which is effectively a self-gating process.
The electron biprism consists of a fine, positively charged electric filament ( represented as a dot in the figure ) bracketed by two plate electrodes at ground potential.
The "'Schmitt Conway Danzer biprism "'( also called a SCD prototile ) is a polyhedron topologically equivalent to the gyrobifastigium, but with parallelogram and irregular triangle faces instead of squares and equilateral triangles.
Overall, a number of things occur in the crystal : First, the two beams or pulses from the biprism are being crossed at a very large angle which acts as a single-shot autocorrelator, self-gating the pulse to produce varying delay in the horizontal direction.
