The core of this system is an improved version of a multi-kilowatt fiber green laser pointer laser. With the “spectral beam combination” technology, the United States will develop high-power fiber lasers that can be widely used in the military field. New York scientists have successfully developed a new chip-based methane spectrometer. Scientists from the Yorktown Research Center in New York have developed a new methane spectrometer that is smaller and more economical to manufacture than standard spectrometers today.
In the Optical Society’s high-impact factor journal, Optica, researchers detailed the new spectrometer and showed that it can detect methane gas at concentrations as low as 1 / 10,000th. US researchers have developed a compact spectrometer for planetary explorationOn December 21, news from Hampton, Virginia, states that a compact spectrometer for planetary exploration has been developed.
The system is called a Positioning Ultra-Miniature Miniature Raman (SUCR) instrument, which can detect and identify minerals, organics, and biological materials within a few centimeters (2-20 cm) with a resolution of 10 microns. The active remote sensing system consists of a 532 nm laser and a miniature spectrometer. The University of Hawaii’s compact instrument directly connects all optical components to the spectrometer. Compared with fiber-coupled Raman systems, the performance of the green laser pointer system has been significantly improved due to less signal loss.
