Fourier Packets
Description
APPLICATIONS
The Fourier Packet is ideal for researchers who need a ground-level introduction to bench-top Fourier Analysis. The packet is the perfect way to gain practical R & D experience in the basic operative principles of optics.
DESCRIPTION
The diffraction patterns generated by viewing a point source through these apertures at a distance of 18 inches are shown on the left. Aperture substrate materials include nickel, stainless steel and brass. Each is mounted on a 1 inch diameter blackened disc, providing a 1/4 inch diameter aperture opening.
