Goal and objectives of the project

- Understanding and manufacturing a high resolution Raman scattering spectrometer (spectral resolution < 20 cm-1) using excitation sources that are semiconductor and monochromatic lasers of different wavelengths.
- Designing and, constructing a holder of the liquid or solid samples with random movable detective points, which is controled by embedded software or a computer to limit the breaken sample.
- Studying and developing the method to detect and qualitative analysis to aim quantitative analysis of normal explosive substances.

Main results

-    Theoretical results: Know-well the technology of designing and manufacturing a micro-Raman spectrometer using two excitation wavelengths 650 nm or 780 nm including modular structure and control software, data processing algorithms form of deep-learning.
-    Applied results: Testing to identify some explosives and explosives precursors. Build a library for the machine to identify some explosive materials.
