Imaging spectroscopy allows spatial and characteristic information to be included in an image from which the sample characteristics can be derived. In this study, a method to improve the signal-to-noise ratio of a spectral signal obtained by using imaging spectroscopy is proposed and demonstrated experimentally. Imaging spectroscopy method using spatial information was found to have a signal-to-noise ratio compared to the conventional spectroscopy method that obtains an average value by using a single photo-detector. Because the spatial distribution information of the sample is known in imaging spectroscopy, unnecessary spectral signals can be removed, and the signal-to-noise ratio can be improved.
