“…During this period, the absolute temperature progressively shifts until it is stabilized. As such, it is necessary to consider how environmental variables affect the registered temperature values, especially during a long acquisition period [37], and take into account wind effect, varying cloud cover, position, and orientation of the sensor during the UAV flight. To remove thermal drift effects and simultaneously apply radiometric correction, some authors program UAV flights to cover ground targets with known temperatures.…”

The development of lightweight sensors compatible with mini unmanned aerial vehicles (UAVs) has expanded the agronomical applications of remote sensing. Of particular interest in this paper are thermal sensors based on lightweight microbolometer technology. These are mainly used to assess crop water stress with thermal images where an accuracy greater than 1 • C is necessary. However, these sensors lack precise temperature control, resulting in thermal drift during image acquisition that requires correction. Currently, there are several strategies to manage thermal drift effect. However, these strategies reduce useful flight time over crops due to the additional in-flight calibration operations. This study presents a drift correction methodology for microbolometer sensors based on redundant information from multiple overlapping images. An empirical study was performed in an orchard of high-density hedgerow olive trees with flights at different times of the day. Six mathematical drift correction models were developed and assessed to explain and correct drift effect on thermal images. Using the proposed methodology, the resulting thermally corrected orthomosaics yielded a rate of error lower than 1 • C compared to those where no drift correction was applied.

“…This type of camera was originally developed for military use. They are small in size, light weight, provide real time output, low power requirements and are inexpensive (Zalameda and Winfree, 2005). Their use in studies of ectotherm thermoregulation is therefore likely to increase in the near future.…”

“…In this detection range, novel narrow bandgap sensing materials are required, because conventional silicon devices can only detect visible and NIR regions. Previously, vanadium oxide (VO x ), [ 162–164 ] indium antimonide, [ 165 ] and mercury cadmium telluride (HgCdTe) [ 166,167 ] have been used in microbolometers for the detection of thermally emitted IR radiation and in imaging chips for mid‐wavelength IR detection. However, these technologies are relatively expensive and require cooling.…”

Recently, photonic technologies have attracted lots of interests in the demand of high‐performance sensor devices. In particular, multifunctional photodetectors based on low‐dimensional nanomaterials have enabled to address complex environmental conditions and data processing for wide range of emerging applications, such as soft robotics, biomedical devices, and neuromorphic computing hardware, translating into mechanically flexible platforms that can offer reliable information. Semiconducting quantum dots (QDs) are one of the promising candidates for such photonic applications due to their excellent optical absorption coefficient, wide bandgap tunability, and structural stability as well as high‐throughput production capabilities, such as low‐cost, large‐area, and complementary metal–oxide–semiconductors (CMOS) compatible solution processability. Herein, essential investigations of the emerging photonic devices and systems are presented, focusing on materials, devices, and applications. In addition, diverse hybrid device architectures, which integrate the QD materials with various semiconductors, are fully examined to introduce the newly developed high‐performance wearable photodetectors and neuromorphic applications. Finally, research challenges and opportunities of the QD‐based photonic devices are also discussed, keeping forward‐looking perspective and system points of view.
