“…An SC light source can output intense and coherent white light, whereas an AOTF can extract light containing specific wavelengths by inputting high-frequency electrical signals [20]. This method offers the advantages of easy light transmission to the light guide and the ability to switch electrically within a broad range of wavelengths at speeds ≤1 ms [21]. The combination of an SC light source and an AOTF can also produce visible wavelengths [22].…”

We propose a rigid-scope system that can perform hyperspectral imaging (HSI) between visible to over 1000 nm (OTN) using a supercontinuum light source and an acousto-optic tunable filter to emit specific wavelengths. In this study, the system was developed, and its optical performance verification and classification ability were investigated. Consequently, it was demonstrated that HSI (490–1600 nm) could be performed. In addition, seven different targets could be classified by the neural network with an accuracy of 99.6%, recall of 93.7%, and specificity of 99.1%, when the wavelength range of OTN was extracted from HSI data as train data.

“…Birks and Russell further studied AO interaction in fiber and provided basic design rule for single-stage all-fiber acousto-optical devices [56]. After that, many all-optical acousto-optical devices were proposed and AF-AOTF technology was born [57,58,59,60,61,62,63,64,65,66,67,68,69,70,71].…”
