Second dispatch from BiOS/PW ’09

This is a long week for those of us “all in” at BiOS and Photonics West, but though it’s not even halfway over, I can already tell it won’t be long enough for me to see all that I want to.

This is a long week for those of us “all in” at BiOS and Photonics West, but though it’s not even halfway over, I can already tell it won’t be long enough for me to see all that I want to.

I spent much of today in the Lasers and Photonics Marketplace seminar, wherein leaders of the greater optics and photonics industry reported and forecasted market outcomes, and discussed important developments. Laser Focus World chief editor Steve Anderson predicted that when all the 2008 numbers are in, the biomedical therapy market will reveal a decline of ~5% from 2007 levels, and 2009 figures will decline a bit further to $477 million in sales.

I also got to talk a bit with Claude Boccara of LLTech (Paris, France) following his presentation on an imaging approach his company calls “full field OCT.” It is unusual in that instead of imaging vertical “slices” of tissue (perpendicular to the probe) as do other optical coherence tomography scanners, LLTech’s “en face” approach images horizontally (parallel to the probe). While this inherently involves a limited depth of field, the approach is able to image a larger area and promises better penetration. The system combines the layers to produce the same kind of image cube that traditional OCT systems do—and lets you step through the cube by peeling away vertical slices. LLTech plans to launch its system commercially in 2010.

Oh, and I reported only one of the presentations at Saturday night’s Hot Topics session—so let me fill you in on another: Kishan Dholakia of the University of St. Andrews (U.K.) discussed photoporation (also called optical injection or transfection) of exogenous DNA into a cell, saying it is “set to become a mainstay in microscopy,” thanks especially to “novel light beams and optical technology and control.” Thanks, that is, to beam shaping.

Thanks Barbara for the interesting facts.
As a member of the LLTech I found useful to indicate that we now have a website.

Best,
Charles
