If you are one of those curious lot who always look at
things and wonder, “what’s lying inside?”, then this news is definitely going
to thrill you. In this era of smart phones, imaging technology is soaring to
new heights. Camera is no more just a means of clicking pictures, shooting
videos and developing panoramic images using apps for entertainment. In the near future,
you will be able to use your phone’s camera to see through the walls, or
anything for that matter.
Mobile phones will be endowed with this new technology,
thanks to a new form of computer chip that functions within a part of the radio
spectrum which is known as the terahertz range. The wavelength of radiation
lying within this range is shorter than high-frequency radio and longer than
that of infrared light.
