Answer 1

X-ray cameras on lampposts plan

The Government is considering installing X-ray cameras on lampposts to spot armed terrorists and other criminals.

According to a leaked memo seen by The Sun, "detection of weapons and explosives will become easier" if the scheme drawn up by Home Office officials is adopted.

However, officials acknowledged that it would be highly controversial as the cameras can "see" through clothing.

"The social acceptability of routine intrusive detection measures and the operational response required in the event of an alarm are likely to be limiting factors," the memo warned.

"Privacy is an issue because the machines see through clothing."

The Sun reported that the memo, dated January 17, was drawn up by the Home Office for the Prime Minister's working group on security crime and justice.

It noted that some technologies used for airport security had already been used in police operations searching for drugs and weapons in nightclubs.

Answer 2

Light colored clothes reflect most of the light rays. This is how we see, by light reflected to our eyes. White cotton and polyester both reflect all colors of light.
An infrared camera picks up the heat rays given off by the body. You can see an image, but it not like seeing a person without clothes. Infrared is a heat ray, below red on the electromagnetic spectrum.
Light does not go through skin , it can go through loosely woven materials.

Answer 3

Infra red. Some Sony video cameras had remove able infra red filters that would show somewhat of a silhouette of people and objects through a covering. Don't get excited, the image was not good. I believe Sony fixed that so they are not removable.
