The system for multispectral imaging is one of the many ways of digitizing cultural heritage. It can retrieve information that is barely visible or invisible to the human eye which makes it an ideal tool for studying historical documents that often carry great damage. It is a hardware and software system that combines data obtained during infrared, ultraviolet and visible light imaging. Thus, the imaging of samples is done using a multispectral camera with filters that allow only a certain, very narrow range of wavelengths of light into the camera and software on a computer that displays the obtained photo. Further processing of the recorded photos emphasizes the elements under study while isolating the rest of the photo. This paper was made in collaboration with the Croatian State Archives in Zagreb and summarizes the process of processing the element that included a manuscript dating from the 17th century. The manuscript was recorded with a total of 36 optical filters. This thesis tries to explain the importance of multispectral imaging which can bring superior results than traditional, analog methods of digitizing cultural heritage. Also, the thesis shows the great role of multispectral imaging in the preservation of the original, considering that in this way we do not cause any damage to the original samples by recording and thus the preservation of the original is not at risk as with analog digitization methods. For this reason, we can say that multispectral imaging is a non-destructive, non-invasive and non-contact method and it can be used to achieve a further understanding of historical materials.
