When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands

Usage examples of diffraction.

Lang and Bresson and Deren but the anti-New Wave abstracters like Frampton, wacko Nucks like Godbout, anticonfluential directors like Dick and the Snows who not only really belonged in a quiet pink room somewhere but were also self-consciously behind the times, making all sorts of heavy art-gesture films about film and consciousness and isness and diffraction and stasis et cetera.

The colored beryllium metal of the wall had been ruled with 20,000 lines to the inch, mere scratches, but nevertheless a diffraction grating.

Luna is a silvery iridescent sphere, planed smooth down to micrometer heights, luminous with diffraction patterns.

Outer Kingdom, from a variety of sources, but all of it contributed to the same purpose: It surveyed the microscopic world through X-ray diffraction, electron microscopy, and direct nanoscale probing, and synthesized all of the resulting information into a single three-dimensional view.

In realistic situations, this diffracted starlight is much stronger than the light from planets around the star, and because of diffraction effects a circular disk is not useful as an occulter in searching for extrasolar planets.

This is done by the smoothing or tapering of the sharp edge of the occulter in such a way that the waves from different regions tend to cancel and diffraction is suppressed.

Moreover, even if the occulter developed many pinholes, the diffraction effects would spread the penetrating light over an area much larger than the images of interest, reducing its effect.

If so, the logical step for us is to go back to the beginning of our tests and rerun our diffractions to see if we can refine our measurements of positron frequencies.

CHAPTER 16 T~tE DEFIANT'S ~ viewer showed the speckled plasma field, complete with flares and clusters and rippling diffractions of every scientific description.

We isolated, and even crystallized the virus, got X-Ray diffractions, did epidemiological studies, all in strictest secrecy.

The real was only probably real, a nexus in endlessly expanding diffractions of the could-be.

The machine's computer began loading the diffraction data into the GeneDyne net, where it was sent across a dedicated land line at 110,000 bits per second to the GeneDyne supercomputer in Boston.

At one moment it would be as flat and featureless as polished steel then it would become flooded with iridescent, rainbow colors, behaving like a giant diffraction grating.

Its metallic limbs gleamed with the rainbow iridescence of a diffraction grating.

I saw that a shaft of red light, split out and deflected by his prism, shone through a diffraction grating and cast an angular pattern of dots and lines on a scrap of smooth plastic behind.
