Is Photonics Doing Enough For Security?

Sure. They oughta take "x-ray" photos of everybody passing through security checkpoints, and just project them on a screen everyone can see. 1) Easier to detect dangerous items. 2) It will force people to get over body image hangups. 3) Don't like what you see? Shape up! 4) Relieves boredom at airports and the like. 5) Less demeaning than pat-downs or body-cavity searches. 6) How about an applause/whistle meter for gorgeous/hunky bods?

I think the terahertz imaging should become mandatory. People who have issues with their privacy have plenty of other options, buses, trains, boats or walk, swim or stay home for all I care but let the rest of us be safe in the sky.

It is doing what it is suppose to do. We have more potential in this field. Our and ours kids life will be safer when photonic and MEMS merges together and bring next generation sub NANO photoanic

OK, here's my plan for air travel security. Everyone travels nude. No carry-on baggage. Your baggage follows on a different flight. To prevent timed body-cavity devices being effective, no flight schedules are to be published in advance (any body cavity device would have to be activated by some sort of timer, since one would not be able to carry an external activator). So, you make your reservation, show up at the airport when told to, strip, pack your clothing into your luggage, check the luggage in, and wait for some unspecified time (we could probably safely limit the wait period to no more than 3 days for the convenience of our normal passengers not bent on terrorist acts). The luggage could actually be shipped on an earlier flight, but perhaps we don't want to make this standard practice, because then we introduce a bit of predictability to the travel experience, which could possibly empower a really clever terrorist). We could ease the agony of the extended wait by providing free booze to passengers (paid for, of course, through a combination of increased air fares and government subsidy)...

We do not run away for challange from crimnal.

We improve our safety measures and teach world we can not only make plane safe globaly but also develop systems which will make train, bus and car safe.

We always makes law when we see new crime and find a detection method of crime and origion.

See Google currently digged in to find who did what was not suppose to be done and for sure we can make tools and install in front of airport, train and bus station and pick up bad guys.

We need to dream and then follow that dream this is in my world in inovation and invention and I live to do this

The sad thing is that people fear the minuscule danger of a terrorist bomb on a plane then they do making a quick trip to the grocery store. Which is more likely to result in injury or death??

According to the US National Highway and Traffic Safety Administration 25,576 people died in traffic accidents in the US in the first three quarters of 2009.

Although a significant decline over the previous year, and a continuation of a trend downward since 2005, this represents thousands more deaths than any number of plane bombings.

If we fear death and destruction at the hands of others, spending the billions we do on security at airports would be better spend crash-proofing cars, installing distance limiters, or whatever other technologies would reduce fatalities caused by "other drivers" (because everyone knows that they would never cause an accident and kill themselves or other innocent people).

If the government spent cash in this area instead of more on airplane security, the savings in life and limb would be enormous benefit to society.

Amin to this. Will agree with every thing youi said

Has anybody done any studies on the health effects of body scanners? Probably not.

Do people who fit the suspicious profile get proper attention?

Should they really be spraying neurotoxic sprays onboard to kill lice, bugs, etc?
