Light Detector has Unprecedented Performance

Really interesting concept, being able to cheaply detect terahertz rays (below heat but above microwaves). These rays tend to pass through the surface of most materials and are reflected from deeper within, so once this is worked out in detail we can probably use it to take pictures of people’s insides without exposing them to X-rays. Of course, it may also allow people to see right through cloths, so the good-old ‘XRay’ glasses might finally become a reality.
