Abstract

In this work, a hyperspectral imaging spectrometer, operating between the wavelengths of 400-1000 nm, with low astigmatism value, and cross Czerny Turner arrangement, is designed and a prototype is produced. This prototype consists of lens, spherical mirror, slit, diffraction grating, cylindrical lens and CCD camera. In the experimental study conducted within the scope of this work, a scene consisting of artificial and natural leaves is scanned by the produced hyperspectral imaging spectrometer, and artificial and natural leaf discrimination is achieved via unsupervised hyperspectral image processing.
