“LIBS is a scientific method that analyzes the composition of matter by exposing it to intense laser pulses. A high-energy laser pulse is focused onto the surface of matter, such as rock or soil. It creates a hot, localized plasma,” Islo said.
The collected plasma light is spectrally resolved and detected by a detector such as a charge-coupled device. “Each element emits a characteristic set of wavelengths of light when in the plasma state, thus determining the elemental composition of the material,” added Islo.
Other elements were also detected
The space agency has confirmed the presence of aluminum (Al), sulfur (S), calcium (Ca), iron (Fe), chromium (Cr) and titanium (Ti) on the lunar surface through preliminary graphical analysis. announced that it has been clarified. .
“Further measurements revealed the presence of manganese (Mn), silicon (Si) and oxygen (O). hydrogen It’s in progress,” Isro said.
The LIBS instrument was developed at the Institute of Electro-Optical Systems (LEOS), Bangalore. One of Isro’s key divisions, LEOS, is responsible for the design, development and manufacture of attitude sensors for all LEO, GEO and interplanetary missions. develops and provides optical systems for remote sensing and weather payloads.
“The laboratory is equipped with world-class manufacturing, testing and coating facilities, including three-axis fiber optic gyros, optical communications, MEMS, nanotechnology, detectors and the development of scientific payloads for future space missions. Next-generation technologies are also being pursued,” said Islo.
