Abstract

The bachelor's thesis deals with the research of the principles, properties and uses of hyperspectral cameras. Unlike conventional color cameras that record three spectral channels (RGB), hyperspectral systems provide tens to hundreds of spectral bands for each pixel, thus enabling the identification of material and chemical differences invisible to the human eye. The thesis covers the basic principles of hyperspectral imaging, an overview of the main technological approaches and their advantages and disadvantages in terms of spatial and spectral resolution, imaging speed, lighting requirements and data intensity. Furthermore, a comparison of commercially available hyperspectral cameras is made based on key parameters such as spectral range, number of bands, resolution, imaging technology and integration options into measurement or industrial applications. The thesis also includes research of scientific articles focused on applications of hyperspectral imaging, for example in the field of materials sorting, food, agriculture, medicine or industrial quality control, and an overview of practical commercial deployments. The result is an assessment of the current state of knowledge, identification of main trends and limitations, and naming the areas in which hyperspectral imaging has the greatest application potential.
