- High quality infrared (IR) quantum detectors are important for several applications, such as atmospheric remote sensing, chemical detection and absorption spectroscopy.
- Imaging in the short wave infrared (SWIR) can bring useful contrast to situations and applications where visible or thermal imaging cameras are ineffective.
- Snow microstructure is an important factor for microwave and optical remote sensing of snow.
- The development of efficient near-infrared (NIR) emitting material is of current focus.
- Terahertz (THz) wavelengths have attracted recent interest in multiple disciplines within engineering and science.
- With the rapid development of nanotechnology, the unique rare-earth lanthanide-doped upconversion nanocrystals (UCNs), which can convert tissue-penetrable near-infrared (NIR) photonic irradiation into ultraviolet, visible, and NIR emissions, have a significant potential in bioimaging, diagnosis, and therapy, as well as in photovoltaic systems and optical data storage.
- Knowledge of the atmospheric transmission precisely at laser emission wavelengths is very important in many laser experiments.
- Although diffraction grating and Fourier Transform spectrometers are widely used in the infrared & far infrared, both techniques posses inherent disadvantages.
- Size and size distribution control along with the excitation/emission wavelength manipulation are the most indispensable for both fundamental research and applications of upconverting nanophosphors.
- Fast and sensitive infrared (IR) photodetection is of interest for depth imaging that is fundamental to machine vision, augmented reality, and autonomous driving.
