It does not need multiple machines, but its application can obtain far reaching results in different fields including food sector. It can be used in food analysis. The LIBS is an atomic emission spectroscopic technique which uses a focused pulsed laser beam to generate plasma from the material. He said this technique was also used in Chandrayan to know the surface composition of moon. The US has also equipped its spacecraft to be sent to the mars in 2021.
