Infrared HgTe colloidal quantum dots (CQDs) are attracting great interest due to their
synthesis scalability, mechanical flexibility, wide spectrum tunability, and excellent …

Dichroic circular polarizers (DCP) represent an important group of optical filters that transfer
only that part of the incident light with the desired polarization state and absorb the …

We demonstrate a wide viewing angle polarization interference filter (PIF), which consists of
two crossed polarizers and double liquid crystal layers with opposite twisted direction. The …

Narrow bandpass filters (NBFs), which are designed to accept a narrow wavelength range
and simultaneously reject a much wider range, show great potential in applications such as …

We propose a composite color filter to achieve the wide color gamut and high optical
efficiency of liquid crystal display (LCD). The composite color filter comprises a multi-layer …

We propose two polarization interference filters (PIF_1 and PIF_2) used in the backlight unit
of a liquid crystal display (LCD) to achieve a wide color gamut. Both PIF_1 and PIF_2 consist …

Spectral imaging allows data acquisition at any particular frequency range in the
electromagnetic (EM) spectrum to extract additional information. The light energy emitted …

Multispectral imaging involves capturing the same scene at different wavelengths using
various narrowband filters stacked or integrated into digital camera sensors. This technology …
