Acousto-optic tunable filter-based hyperspectral imaging system characterization

This work describes a procedure to characterize a developed acousto-optic tunable filter (AOTF) based hyperspectral imaging (HSI) system, operating in the visible-near infrared (VNIR) spectrum. The developed AOTF-HSI system consists of an AOTF (11 × 12 mm aperture), a set of optics, and a computer. The AOTFHSI setup includes a complementary metal oxide semiconductor (CMOS) camera (2048 x 2048 pixels), a zoom lens (55–250 mm f/4–5.6), and an …
