A hyperspectral camera is an analytical instrument used in the field of physics with fast data acquisition and processing capabilities. It is equipped with standard signal acquisition software to collect and simply process hyperspectral images and spectral data in the way of push broom imaging, which can obtain sample spectrum and image information in real time, and store the scanning results in various formats such as images and images. It has the advantages of wide spectral range, good spectral linearity, fast imaging speed and high resolution. The data of this imager can also be called up by a variety of third-party professional data analysis software, which greatly expands the scope of use of the instrument.
Specifically, the function of the hyperspectral camera is to organically combine spectral technology and traditional two-dimensional image technology, and the obtained hyperspectral image contains both spectral information and image information. The main function of this imager is to measure the spectrum of ground features such as vegetation, crops, soil, rocks, and water bodies. Therefore, it is widely used in industrial sorting, precision agriculture, color difference detection, food testing, medicine and pharmaceutical, cultural relics protection, criminal investigation detection, environmental monitoring and other fields.
The working principle of hyperspectral cameras is to focus the light reflected and scattered by infrared radiation or visible light through the optical imaging system to a special spectrometer, and then decompose it into different wavelengths of light through the spectral instrument. Under the control of the hyperspectral camera, different wavelengths of light can be collected separately and a spectral information image of the target object can be established. At the same time, the hyperspectral camera can also obtain spatial information images of the target object.
The advantage of a hyperspectral camera is that it can obtain detailed spectral information about the target object, so as to better distinguish between different substances. For example, in the field of geological exploration, by collecting spectral information of rocks or soils, their chemical composition and structure can be determined, and then their regional distribution and geological environment can be determined.
In the field of agriculture, hyperspectral cameras can be applied to the growth monitoring of crops and the identification of pests and diseases. By capturing hyperspectral images of crops, it is possible to understand the health and growth of plants, as well as certain elements that crops are lacking. At the same time, the hyperspectral camera can also better distinguish the spectral information of plants and pests and diseases, so as to identify and monitor pests and diseases more accurately.
In the medical field, hyperspectral cameras can be used for the detection of tumors and**. Since the spectral characteristics of tumor tissue are different from normal tissues, hyperspectral images of tumor tissues can be collected to distinguish tumor tissues from normal tissues well. At the same time, hyperspectral cameras can also be applied to photothermal and photodynamic medicine to improve the effect and reduce the trauma to patients.
Hyperspectral cameras are a very promising optical imaging technology. It can obtain spectral information and spatial information of the target object at the same time, and can be applied to many fields, such as medicine, scientific research, geological exploration, environmental monitoring, agriculture, etc. In the future, hyperspectral cameras will become more and more powerful tools in various fields.
