What is Terahertz imaging? Use of Terahertz imaging in reading closed books?
Terahertz Imaging can be used to read Closed Books which are Old Terahertz imaging is a technology which makes use of the Terahertz frequency which ranges from 0.1 THz - 3 THz and lies between the microwave and infrared frequencies. Terahertz frequency is able to see through many materials which are blocked by visible and infrared spectra which make it beneficial to be used for terahertz imaging. Thus, compared to the microwave radiation or the conventional X-rays, it is able to achieve better spatial resolution which is required for rendering quality imaging with the help of T-rays or terahertz frequency range. Now, if we want to know the depth of the mine which we dug, we would send laser in the deepest point and then measure the time it takes to travel back to the source. As we know the speed of light, we can ...
