• LIBS technique has applications in diverse areas such as forensic elemental analysis, environmental monitoring, real-time radioactive material tracking etc
• LIBS has advantages such as multi-element detection capabilities, in-situ analysis, minimal sample preparation requirements, minimal destructiveness, high detection sensitivity, and the ability to perform remote detections
• Distance and height of the systems remains as a major hurdle  while finding a robust solution for pollutant detection on moving and rotating objects or targets

The present invention discloses a device for determining the elemental identity of optical emission generated by a laser beam irradiation on a moving target with a variable stand-off distance, the said device arrangement comprising of:

• An irradiating laser trigger means
• Adjustable focusing optical means
• A fixed aspheric mirror means
• A moveable beam diverting mirror means
• A holder means
• Optic fiber connected to optical emission
• Spectrometer associated with optic fiber
• A data acquisition means

1. Laser Induced Breakdown Spectroscopy (LIBS) technique is combined with a photometric device for determining the presence of various elements and analysis of moving target material from a variable remote distance
2. Said technique is combined with temporal and spatial studies is demonstrated for detection and quantification of a salt deposit on a GFRP material.
3. The irradiating laser trigger means transmits laser beams towards the moving target
4. The adjustable focusing means includes focus mirror  and a focusing lens to focus the transmitted beams from the laser trigger means on to the moving target
5. The irradiating laser trigger means transmits laser beams towards the moving target
6. The adjustable focusing means includes focus mirror  and a focusing lens to focus the transmitted beams from the laser trigger means on to the moving target
7. Further, the said transmitted beams induce plasma plume emission on the surface of the moving target
8. The fixed aspheric mirror  focusses the induced plume emission from the surface of the moving target
9. The movable beam diverting mirror means, which is two sided mirror receives the focused plasma emission from fixed aspheric mirror 
10. Spectrometer captures signals corresponding to plasma emission of the moving target , and the data acquisition means receives and stores the signals from the spectrometer
