    When we saw Dr. Liu Hongfei, Dr. Liu just received a phone call from the Organizing Committee of the China Innovation and Entrepreneurship Competition to inform Dr. Liu Hongfei on behalf of the Optosky Photonics Inc. (www.optosky.com) with excellent results. Directly advanced to the finals and represented Xiamen in the China Entrepreneurship Competition.

1. Raman spectroscopy is commonly used for qualitative testing and can also be used for quantification under certain conditions.
2. Raman spectroscopy can be used for microscopic analysis with spatial resolutions on the order of 0.5 μm to 1.0 μm.
3. Raman spectroscopy can be used for macroscopic large sample analysis.

Raman spectroscopy can be obtained for solid, liquid, gas, mixed material samples, and aqueous samples.

The Raman spectroscopy technique used in this study used the similarity (HQI) algorithm to establish three methods for the identification of pharmaceutical excipients. Collection three

The Raman spectra of the excipients and their common adulterated components are visually identified and similarly discriminated by the map alignment, and finally the fitted curve is established.

Line and function, and preliminary determination of impurity detection limits for pharmaceutical excipients.

This research studies the rapid detection technology of pharmaceutical excipients based on Raman spectroscopy and similarity method, which is very suitable for the single layer of various conditions.

The use of Raman spectroscopy combined with the similarity method provides a new means for on-site discriminant analysis of excipient doping.

Good application prospects.

The rapid inspection method used in this study is only applicable to the analysis of binary systems. How to extend this method to the division of multiple systems

Analysis, and the influence of internal molecular forces after multi-component mixing on Raman spectroscopy, etc., are all what we need to study next.

The fiber Bragg grating sensor has only one fiber, and the sensitive component (grating) is fabricated in the core. From the advantages of small size and light weight, almost no other sensor can be compared. Therefore, the military and aerospace industries attach great importance to fiber grating sensing technology. Only Boeing has registered several patents for fiber grating sensors.
