|optical transform slides
- Shine a laser through various
arrays of dots to show the resulting diffraction patterns.
Compare patterns produced by arrays with different spacings,
There are four slides with eight patterns on each. The manual has
enlarged images of the patterns for use with the document camera, or
one can view the slides with the loupe.
Brief descriptions of slides:
represent 2-D versions of
simple cubic, body-centered cubic, orthorhombic, monoclinic, and
hexagonal close-packed structures
and vertical lines of
different spacings, square arrays of different spacings.
represent triatomic molecules
with different bond angles.
plane groups (blue):
have same size unit cells with
can view the slides themselves using the loupe or, for a large group,
they can be projected with a slide projector.
This set of slides is
intended as an optical analog of x-ray diffraction, as are the Bergsten
"optical crystal" slides.
set of optical transform slides from the Metrologic
Kit that demonstrates aspects of image processing,
spatial filtering, etc.
