The three primary colour model, ie, red, green, and blue model, based on the colour
perception of the human eye, has been widely used in colour imaging. The most common …

Pixel scaling effects have been a major issue in the development of high-resolution color
image sensors due to the reduced photoelectric signal and color crosstalk. Various structural …

Digital color imaging relies on spectral filters on top of a pixelated sensor, such as a CMOS
image sensor. An important parameter of imaging devices is their resolution, which depends …

Near‐infrared multispectral imaging technology enhances target detection and recognition
by distinguishing the spectral characteristics of various targets. However, traditional imaging …

The strong dispersion, ultra-thin form-factor and robustness to degradation make
metasurfaces attractive for color filter applications. In particular, transmission-mode filters …

Color displays have become increasingly attractive, with dielectric optical nanoantennas
demonstrating especially promising applications due to the high refractive index of the …

Optically resonant high-index dielectric metasurfaces featuring Mie-type electric and
