Microscopy News
Did Renaissance Artists Use Optical Projections, Or Didn't They?
Oct 8, 2004 — WASHINGTON, Oct. 8 -- Contemporary artist David Hockney caused a stir in 1999 with his controversial theory that early Renaissance artists used optical devices like the camera obscura or concave mirrors to project scenes onto their canvases for tracing. This, he believes, might help explain the sudden emergence of more realistic painting in the early 15th century. It would also mean that artists began using optical lenses even earlier than scientists did: The microscope and telescope weren't...

Polymer Holey-Fiber Laser Is Easy to Make
Oct 1, 2004 — Solid-state dye lasers, in which the dye is dissolved in a solid host rather than in a liquid solvent, have several advantages over conventional liquid dye lasers, including compactness, robustness and the absence of flammable and volatile organic...
Spinning Disk vs. Laser-Scanning Confocal Microscopes
Oct 1, 2004 — When imaging thick biological specimens, light from out-of-focus planes often obscures the fluorescence of structures of interest. Various confocal methods can remove out-of-focus light to reveal the structures. Different confocal systems allow...
Through the Looking Glass and What Cavity Ringdown Found There
Oct 1, 2004 — What is air? Scientists worldwide continue to focus their attention and their instruments on answering that simple question with an ever-increasing standard for accuracy. It is no longer sufficient to know that air is composed mostly of nitrogen and...
When the Light Fails
Oct 1, 2004 — Proper lighting is an important part of any machine vision system. Obviously, the lighting needs to be adequate, but it also should be arranged so that it amplifies the things you want the vision system to see while attenuating those you don't....
