Micro Video Lenses Grow Up
A few years ago, micro video lenses were used in machine vision almost exclusively for limited-space and low-resolution applications. But the ongoing reductions in size and cost of optical sensors, along with increases in pixel count, are allowing the creation of higher-resolution compact video systems. At the same time, new optical designs are yielding micro video lenses with increased...

And the Nobel goes to ...
Photonics was in the spotlight last month as the Royal Swedish Academy of Sciences announced that the 2009 Nobel Prize in physics would be awarded to three legends in the field: Charles K. Kao, a founding father of fiber optics, who received half of the award, and Willard S. Boyle and George E. Smith, fathers of digital imaging. Kao was cited for discovering how to transmit light through fiber...

Sandfish lizards do the locomotion
Physicists, biologists, mathematicians and engineers have formulas to characterize movement over hard ground, but they still have much to learn about locomotion over more fluid surfaces, such as sand or mud. To find out more, physicists at Georgia Institute of Technology in Atlanta have studied various animals that “swim” in sand, such as the aptly named sandfish lizard (Scincus scincus), a...
