The wavelength-tunable laser only scans wavelengths near the latest wavelength of each FBG sensor. The scanning range is constantly updated to achieve wavelength tracking, and the FBG demodulator ...

By integrating double-sided full passivation, mitigating optical parasitic absorption, and utilizing ultra‑thin busbar technology, the new modules boost cell efficiency by up to 1%, with enhanced ...

Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in the “useful” mid-infrared wavelength range ... The device ...

As part of InSeKT, Fraunhofer IPMS will be evaluating photodetectors for the near-infrared wavelength range. These are used, for example, in material analysis and recycling and even enable analysis ...

Furthermore, the goal of a data-supported evaluation of photodetectors for the near-infrared wavelength range is being pursued. These are used, for example, in material analysis and recycling and ...

The device can make what's called an optical frequency comb ... carbon dioxide and methane absorb mid-infrared light efficiently, this wavelength range has been an important tool in monitoring ...

However, applying conventional near-range imaging algorithms directly to single-frequency measurements leads to defocusing issues and degraded imaging results due to the lack of range resolution.

A new study suggests Earth's oceans may have been green during the Archean eon, around 3.8 to 1.8 billion years ago. The greenish hue was due to high iron content and early microbes performing ...
