New discovery about terahertz radiation benefits biomedicine

Scientists from ITMO University for the first time in the world managed to directly measure the nonlinear refractive index of matter in the terahertz range. The results of the experiments were compared with previous theoretical ...

Precise temperature measurements with invisible light

Ordinarily, you won't encounter a radiation thermometer until somebody puts one in your ear at the doctor's office or you point one at your forehead when you're feeling feverish. But more sophisticated and highly calibrated, ...
