Conversion of infrared to visible light possible with new breakthrough

Posted by in categories: innovation, mobile phones

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

Electromagnetic waves have a characteristic frequency and wavelength that are inversely proportional; as one increases, the other decreases. Measured in Hertz (Hz), human eyes can perceive light frequencies between 400 and 750 trillion Hz, or terahertz (THz). Smartphone cameras can detect down to 300 THz, and other detectors used in fiber-optic cables can detect around 200 THz.
