“…In HSI of agricultural crops, photonic detectors are commonly used for monitoring. Different types of detectors have been proposed; in particular, chargecoupled devices (CCDs) that are made from low-cost lead oxide-lead sulfide (PbO-PbS), indium gallium arsenide (InGaAs), or mercury cadmium telluride (HgCdTe or MCT) have been commonly applied to determine the amount of light emission or absorption at particular peaks throughout the spectrum (Casini et al, 1999;D'Souza et al, 1999;Sizov, 2000;Gat, 2000;John et al, 2003;Tran, 2003;Bajwa et al, 2004;Rogalski, 2004;Xenics, 2016). In this technique, it is important to identify a distinct spectral range and obtain particular peaks from the spectrum.…”
