Isn't there any instrument which can see thro' clothes?

Question

If there is, why is police not using it to detect human bombs?

Answer 1

other than X-ray, around 2 years ago UK made an instrument to use in the airport, but the goverment and people didn't let them to use it.

Answer 2

Be careful of your wording. Instruments can not 'see' through anything as they don't have eyes. You should have said:

'Are there any instruments with which one can see through clothes?'

Also, what is a human bomb?


Anyway, enough nit-picking. Most people here have mentioned the X-ray, and that's fine. They also use ultrasound to see through clothes. Ultrasound, unlike X-rays, is not electromagnetic in nature. Whilst an X-ray will pass through clothes, skin, muscle and brain and only be impaired by bone (because bone is mostly calcium, and calcium is a metal, so it has a negative permittivity and a positive permeability, meaning it has a complex attenuation term in the Drude model of the tensor description of the metal's electromagnetic behaviour), the ultrasound's penetration depends more strongly on the energy of the ultrasonic beam (yes, it is a beam as you can produce spatially solitary sonic waves).

So, by varying the intensity of your ultrasound beam you can choose how far through someone you would like to visualise. This, coupled with a computer to analyse the echo in real time, means you can get very accurate 4D images of people without their clothes on if you so wish.

The technology is in its early stages of development right now, as creating a sonic spatial soliton isn't a trivial task, but close-range ultrasound devices are used in hospitals now to visualise an unborn child in 4D, unlike the old ultrasound (3D, two spatial and one temporal).

And that's all I have to say about that.

Answer 3

Yes, I purchased a pair of X-Ray Specs from an ad in the back of a comic book back in 1976. I was in second grade at the time, and these special glasses allowed me to see through people clothing just like the ad stated. The only problem with these galsses is the black and white vortex pattern on the outside of the lenses that tips everybody off to the fact that you are in fact looking at them naked.

Answer 4

You cant see through just the clothes, infact you can see through flesh and muscles too but not the bones. This is done by incidenting X-rays on the fellow. X-rays are high-energy, short wavelength radiations that can pass through anything but bones in human body.

Answer 5

It is called X-rays and it is used at Several places to check Ur belongings as its long term radiation is harmful to human body so it is not used for checking on the Human Body.
U can find X-ray machines being fitted at several places of importance as:
AIR PORTs
TIRUPATI BALA JI Temple
VAISHNO DEVI Temple
......
for checking the luggage.

Answer 6

if you are of a certain age (cough) likely enough when you went to a shoe-shop they would have put your feet in a fluoroscope to check the fit. this used x-rays to see right through your socks and shoe-leather so you could see your feet wiggling inside your new shoes!
also handy for detecting shoe bombers perhaps!

Answer 7

yes there is a mobile in japan which can see through clothes.actually the mobile has a night vision camera which when attached to high end camera can see through clothes.but one thing is that it cannot see through all clothes.For more information go on the site given below.

Answer 8

Oh yes, I believe, that there is a Video recorder ( hand held ) that is able to do just that, I had one that did just that it had 3 light settings on it, and one could do just that. so it can be done, but won't use it for ethical & religious reason UNLESS , they need to!!

Answer 9

well they use it to perve on others... LOL

less streangth X-Ray machines can do this. But it's expensive (bulk?) and harmfull to humans (excess exposure). but in high sequrity areas like in airports they use them to scan bagages & stuff.

Answer 10

If you find out let me know. I think the answer is no
