Practical Focus Adjustment Method for Hyperspectral Cameras

In order to get a clear picture from the cameras, many settings need to be done correctly. One of the most important of these settings is the focus setting. If the focus is not set correctly, blurring occurs on the images, which causes shape information to not appear clearly. Focus adjustment is critical for hyperspectral cameras as well as for all cameras. In hyperspectral cameras, blur occurs not only spatially but also spectrally, leading to a significant decrease in data quality. In this paper, the focus adjustment process was examined for hyperspectral cameras and a new method was suggested for correct adjustment.
