Fresnel zone plate (FZP) stacking is an approach to enhance diffraction efficiency in x-ray focusing and imaging by physically aligning 2 or more FZPs to increase the effective thickness and optical ...

Researchers have discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These so-called moir patterns can be tuned to look like periodic spots or even one ...

When two mesh screens or fabrics are overlapped with a slight offset, moiré patterns emerge as a result of interference caused by the misalignment of the grids. While these patterns are commonly ...

As the need for higher-resolution orbital imagery expands, glass mirrors are fast approaching the point where they will be too large, heavy and costly for even the largest of today’s rockets to carry ...
