• Ultra High Sensitivity Raman Spectrometer-Even sensitive enough for complex gas Monitoring

  Raman Spectroscopy has been widely used in analyze solid and liquid phase sample, but not so much in gas phase sample . Main problem is, normally, the gas phase molecular under the laser illumination is too much less than the same laser illuminate the liquid or solid phase sample. So that, in generally, the Raman signal scattered from the gas phase sample will be too weak to be detected.

• Analysis of tea tree classification based on UAV hyperspectral Introduction

  UAV hyperspectral can better identify the distribution location of tea trees. The hyperspectral data of tea obtained under good flight conditions is more conducive to analysis and research, and can further improve the accuracy of classification and identification.

• Presentation of thesis results

  Compared with ordinary RGB imaging system, hyperspectral has high dimensional features, information redundancy, significant uncertainty, small samples, and space-spectrum unity, etc., and it faces great challenges for data processing. In recent years, with the emergence of new techniques of deep learning, hyperspectral images based on deep learning have been fully developed in the fields of dimensionality reduction, hybrid image element decomposition and classification.

• Analysis of water pollution research based on UAV hyperspectral

  Water is the source of life, as well as the blood of the ecosystem, is the basis of human survival, production and life. Sufficient quality water resources are the first condition for the healthy cycle of the ecosystem, but water resources are very vulnerable to pollution, especially some inland water bodies, due to the natural closed its pollution problems are more prominent. While the water resources as a carrier of pollutants, with dynamic diffusion and spread characteristics, will further aggravate the degree of pollution of water bodies. There are many rivers and lakes in China, along with the rapid development of the economy and the enhancement of human activities, the problem of water quality pollution in rivers and lakes has become increasingly serious, has become a key factor limiting the sustainable development of cities, so it is necessary to use high-tech means to carry out research on water quality pollution in rivers and lakes, to provide timely and rapid water quality conditions in rivers and lakes, to protect people's normal production and life.

• Airborne hyperspectral water body image stitching and content inversion

  Water is the source of life, and as the blood of the ecosystem, it is the basis of human survival, production and life, and sufficient and high-quality water resources are the primary condition for the healthy cycle of the ecosystem. However, water resources are very vulnerable to pollution, especially some inland water bodies, due to the natural confinement of its pollution problem is more prominent, while water resources as a carrier of pollutants, with dynamic diffusion and spread characteristics, will further aggravate the degree of pollution of water bodies. There are many oceans and lakes in China, along with the rapid development of the economy and the enhancement of human activities, the problem of water quality pollution in oceans and lakes has become increasingly serious. It has become a key factor limiting the sustainable development of cities, so it is necessary to use high-tech means to carry out research on water quality pollution in oceans and lakes, to provide timely and rapid water quality conditions in oceans and lakes, to protect people's normal production and life.
