The Hidden Truth

Brain imaging may become ultimate lie-detector test

By Barry Hochfelder

As explained by Nathalie Combrousse of Varioptic, liquid lenses are characterized by a very wide range of focal lengths that enable very close focus, high optical quality, fast and consistent response, and are very robust with no moving parts to wear or break.

Those of you who are fans of our Industry News department might be dismayed not to see it in this issue. However, you can find all the updated news you want by visiting our web site, Because news is so fluid and constantly changing, we're going to put in on the web where you can check it as often as you like.

Also on the site this month is a web exclusive, a feature story that won't appear in the print publication. It's an additional piece from our Optics Technology Report on Tessera's optical zoom. This technology allows the user to artificially "get closer" to a distant object. Magnification is achieved by restricting the field-of-view (FOV) and increasing focal length, making it possible to capture a distant scene without loss of resolution. Most commercial digital still cameras provide optical zoom capability.

As always, contains thousands of products in addition to those that we run in the magazine. Please visit the site often to take advantage of all the electronic imaging technology our industry has to offer. And, if you have any questions or comments, please contact me at
