Abstract
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 AOTF radio frequency synthesizer. Two multifaceted reflector tungstenhalogen lamps (150 W) were used to provide double-sided illumination to the region of interest. Image acquisition was accomplished by a home-made C# code. The code enables imaging of samples in the VNIR (450 – 850 nm) range in both hyper/multi-spectral modes. The developed spectral imager presents a valuable opportunity for noninvasive evaluation of medical samples.
