Professor Jim Palmer

Guest Lecturer for Class 5

 
Professor Jim Palmer is a Research Professor here at the Optical Sciences Center.  He is a world-expert in the areas of radiometry and photometry, the science of how light is generated, transported, and detected.  Photometry deals with visible light that the human eye can "see," and radiometry deals with all other wavelengths, in particular, the infrared.

We welcome him today to talk about the subject of color.

Software used in class:

In class we used a program called "CVD2" that showed a variety experiments with color--mixing, additive, subtractive, and illusionary effects.  In particular, we demonstrated the following topics found in the program's menu:

"After Effects & Opponent Colors" (page 1 of the menu)
"Induction after Adaptation" (page 1 of the menu)
"Flicker Photometry I : Stripes" (page 2 of the menu)
"Flicker Photometry II : Checkerboard" (page 2 of the menu)
"3-Color Mixer" (page 2 of the menu)

To run each of these:  "left-click" on the topic in the menu, which will bring up the screen.  If "Spec" appears at the top, left-click on it, stare at the effect, then left-click again to move to the next screen.  Use the <Esc> key to return to the starting screen, then click on "Menu" to return to the main menu.
