PRESIDENT OBAMA'S STATEMENT ON PASSING OF LEONARD NIMOY

FROM:  THE WHITE HOUSE
February 27, 2015
Statement by the President on the Passing of Leonard Nimoy

Long before being nerdy was cool, there was Leonard Nimoy.  Leonard was a lifelong lover of the arts and humanities, a supporter of the sciences, generous with his talent and his time.  And of course, Leonard was Spock.  Cool, logical, big-eared and level-headed, the center of Star Trek’s optimistic, inclusive vision of humanity’s future.

I loved Spock.

In 2007, I had the chance to meet Leonard in person.  It was only logical to greet him with the Vulcan salute, the universal sign for “Live long and prosper.”  And after 83 years on this planet – and on his visits to many others – it’s clear Leonard Nimoy did just that.  Michelle and I join his family, friends, and countless fans who miss him so dearly today.

NAVAL RESEARCH LABORATORY DEVELOPING "SCIFI-LIKE" LIGHT SCANNER


FROM:  U.S. DEPARTMENT OF DEFENSE ARMED WITH SCIENCE


I SEE THE LIGHT SCANNER
Written on JUNE 29, 2012 AT 7:26 AM by JTOZER

The concept of new technology is something that always grabs my attention, but no more so than when real research suggests that my dramatic daydreams of science fiction technology might actuallybecome a reality.

So when I heard that the Naval Research Laboratory (NRL) was developing a real life scanning device, my first immediate thought was STAR TREK SCANNER!
And then I took a deep breath, reeled it in, and read more.  I mean, come on, that kind of technology is centuries away…right?

As it turns out, NRL’s scanning device isn’t that far removed from Star Trek’s fictitious future world or Doctor Who’s technoverse gadgetry.  Although, instead of being an impressively multipurpose-yet-unfortunately-fictitious sonic screwdriver, this real life device uses light to scan objects from far away.

The Naval Research Laboratory (NRL) has developed a Photothermal Infrared Imaging Spectroscopy (PT-IRIS) technology for stand-off detection of explosives, illicit drugs, chemical warfare agents and biochemical warfare agents. That’s right; technology that can scan for dangerous objects from a distance.  PT-IRIS has been demonstrated for standoff or proximity detection of explosives.

That, my friends, could be a huge help to our troops.
Being able to “scan” for dangerous items from a safe distance – especially when it comes to explosive materials – would be an unbelievable asset to the warfighter.  Service members would have the benefit of knowing what they’re up against long before they put themselves in the blast range.
And it’s all about seeing the light.  In this case literally.

This approach employs quantum cascade lasers (QCL) to illuminate a sample surface with one or more wavelengths which are selectively absorbed by analytes of interest. With eye-safe QCL power levels, this results in modest selective heating (1-2 oC) of particulate explosives within a few milliseconds, which can be readily monitored at video frame rates of commercial IR cameras.

Basically, the PT-IRIS absorbs the information and relays it back.  The idea of no longer wondering what’s on that suspicious van on the side of the road could literally mean life or death for service members.

Utilizing compact QCL light sources and an IR focal plane array to image the illuminated area, a portable, handheld system design can be realized. Don’t leave home without your explosive-detection device!  No, seriously, you don’t want to leave something like that just lying around.

As an eye safe system, PT-IRIS is ideal for probing surfaces of vehicles, places, people, packages, and boarding passes for explosives and other hazardous chemicals of interest.  This technology could be used everywhere, from police stations to airports, to suspicious parents who think their kids aren’t just “high on life” (okay, maybe not that one…).

That’s all well and good, but really I’m most interested in the idea that our men and women in uniform stand the chance of not being blown up as much. Science fiction hopes and dreams aside, if anything can make our service members safer and more effective, then I say hop to it.

This technology could give a whole new meaning to the phrase “Stand off, we got this”
