Stray‐light suppression is a fundamental requirement in a wide range of optical applications, such as astronomical observations, optical communications, high‐precision sensing, and high‐quality imaging. For example, conventional optical imaging systems usually rely on optical baffles to physically block stray light....

Three-dimensional (3D) tracking of microscopic objects is essential for probing dynamic processes across biological, microfluidic, and nanoscale systems. In-line digital holographic microscopy (DHM) provides a powerful framework for this purpose by encoding volumetric information into a single intensity measurement,...
