The Optical Design and Calibration of a Finite-Conjugate VNIR Pushbroom Hyperspectral Camera for Close-Range Cultural Heritage Imaging
Visible–near-infrared (VNIR) hyperspectral imaging provides a non-contact approach for cultural heritage examination. This study presents the design and calibration of a compact finite-conjugate VNIR pushbroom hyperspectral camera for close-range mural imaging. Operating over 400–1000 nm at a nominal working distance o...
