Photonics for a Better World

Ultraviolet image from NASA’s Galaxy Evolution Explorer shows NGC 3242, a planetary nebula frequently referred to as “Jupiter’s Ghost.” Image courtesy NASA/JPL-Caltech Are there any connections between space technologies and healthcare? You bet there is, says Shouleh Nikzad, senior research scientist at NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology (Caltech) and the principal engineer, co-lead, and technical director for JPL’s Medical Engineering Forum. Numerous optics and photonics technologies originally developed for space applications have found their way into consumer and medical markets, Nikzad writes in the April 2017 issue of SPIE Professional magazine . Infrared thermometers, workout machines, compact cameras in mobile phones, and imaging technologies are just a few familiar examples. Ultraviolet imaging is also used in medical applications to reveal disease, as in this image of cancerous brain tissue. ...

You know that signature file you may have – “Sent from my [fabulous device name here]”? Our CEO here at SPIE, Eugene Arthurs, has one that gives credit where credit is due, to photonics: “Multiple laser processes were used to make this iPad. Many photons worked to bring you this message.” This blog makes the case that photonics can make the world a better place, and who can argue with the convenience and ease that is enabled by these great smartphones and tablets? Yes indeed, there are photons aplenty at work. But the latest column from Mark Morford , creatively infuriating (to some) writer for SFGate, points out that those who get worked up over what’s the latest and greatest, and the absolute best, are just wasting their energy, because tomorrow it will be something else. It’s reminiscent of the legend of the conquering Roman generals, who were accompanied in their victory parades by a slave to whisper a reminder in their ear: “All glory is fleeting.” Because, as Morford...
