Abstract: This paper demonstrates a highly sensitive digital readout method for angular displacement measurement using a two-dimensional transmission diffraction grating and a smartphone CMOS camera.

In optical interferometry, waves of a light signal travel to separate light collectors, and the interference pattern formed by superimposing the waves reveals spatial information about the light ...

Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...
