The terahertz region of the electromagnetic spectrum, with frequencies from 0.3 to ~10 terahertz (THz) or wavelengths from 1 mm to 0.03 mm lies between the microwave and the far infrared. In comparison with X-rays they are intrinsically safe, non-destructive and non-invasive. Recent advances in THz sources, detectors and imaging systems have enabled applications ranging from cancer detection and materials characterization to industrial product inspection and even detection of concealed weapons at airports!

Join us online as we visit, TIFR's Fundamental Optics, Terahertz and Optical Nanostructures (FOTON) lab where researchers work on the generation and detection of THz radiation and THz spectroscopy of various different materials. .

About the Speakers: Dhanashree Chemate and Ajinkya Punjal are research scholars at the FOTON lab.
