A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. Their study not only identifies the constraints of conventional sampling ...

When the sampling rate is too low, aliasing artifacts occur, leading to distorted images and ... account for the optical complexities of metasurfaces. While Nyquist theory effectively defines ...

all these different approaches that image beyond the 'diffraction limit' are complementary. One thing is clear: the achievements of super-resolution imaging are narrowing the gap between optical ...

Aliasing artifacts occur when the sampling rate is insufficient, leading to optical distortions and reduced efficiency. A well-known example is the wagon-wheel effect in motion pictures ...
