Through the years, hyperspectral imaging has emerged as a powerful technique for revealing data invisible to the human eye. The technique can be employed either remotely or in-process, and it is commonly used to monitor production to control product quality and output. Traditionally, hyperspectral imaging systems or cameras have been bulky, heavy, and costly. However, recent technological advances are changing that and opening the door to new opportunities in hyperspectral imaging.
