Chalcogenide photonics offers unique solutions for a broad range of applications from mid-infrared sensing to integrated, ultrafast, ultrahigh-bandwidth signal processing. However, to date its usage ...

Use left and right arrow keys to seek audio. In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency than ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

The image fusion technique, as an important branch of information fusion, belongs to the quality enhancement in the image processing discipline. Theoretically, image fusion attempts to integrate ...
