HRL Laboratories recently announced the development of a new diode that will be incorporated into a Passive Millimeter-wave Camera by Trex Enterprises. This new camera allows the user to see through drywall, plywood and eventually even concrete.
This is a technological elaboration and an extension of the infamous Sony Handycam Nightshot 0Lux video cameras circa 1998, which allowed users to ‘bypass’ their subject’s clothing & operate in ‘xray’ mode.
HRL’s innovation is proprietary, but involves the use of indium arsenide and tellurium-doped gallium antimonide to improve the sensitivity of the Schottky diodes that make up each pixel of the image. While the Sonys operate(d) at a wavelength of 750nm, these devices move down spectrum to 1mm, where there is less refraction.
This new camera will be of most use in military and police situations, but I suppose the average person could use them to see if someone is lurking outside their front door – or, vice-versa.

I shudder to think what would happen if this technology fell into the hands of criminals…or frat boys.
