Remember cartoon characters with x-ray glasses that enabled them to see through everything including walls?Well, a graduate research associate at Ohio State University by the name of Georgios Trichopoulos has taken a step in that direction with the help of his mentor, Professor Kubilay Sertel.Trichopoulos designed a camera that can see through any material.The camera works as a video format, eliminating the three-second pausing by passengers and giving airport security screeners a faster advantage over any pre-determined threats.By using a different wavelength of light called Terahertz, a wavelength between infrared and radio wavelengths, the emitted radiation won’t increase the cancer risk that x-ray machines do but also exposes dense materials like metals and less dense materials like liquids.With its built-in sensor containing thousands of tiny antennas, the camera can pick up terahertz radiation and transmit it at the object to be scanned.As the antennas pick up the radiation, it signals the computer to transform it into a pixel.The camera works similar to a digital camera except that the speed in which the thousands of antennas pick up the radiation causing the computer to form a video.The camera can also be an advantage in the health field. Doctors are able to detect tissue by taking a better look at the burned area with this innovative idea.
