Fraunhofer diffraction from a sensor array with a 6 um pixel pitch at 45� incidence. Zero-, plus- and minus-orders are visible. Samuel F. Pellicori, Pellicori Optical Consulting
Scatter distribution from um-thick films of Cerium Oxide layers that were deposited at oblique incidence. Laser beam enters the edges of two film layers that face each other. Samuel F. Pellicori, Pellicori Optical Consulting
Sunrise illumination of man-made and natural clouds. Samuel F. Pellicori, Pellicori Optical Consulting
A double sunbow seen in New Port Richey Florida. Ray Williamson, Ray Williamson Consulting
Sunset in the Lab: The Tyndall-Rayleigh experiment. View of the set-up and several stages of the experiment. Notice the strong polarization of the scattered light and the change of color of the beam. Juan Carlos Barreiro, Optics Department. University of Valencia, Spain
4kW, 810nm diode laser power beaming system with automated beam steering, used to win NASA Power Beaming Challenge. Tom Nugent, LaserMotive, Kent, WA.
White light diffraction produced by a multi-domain monolayer made of 1 micron polysterene spheres in HCP packing. Victor Canalejas Tejero, CSIC, Madrid, Spain.
