Applications of optical logic-operated moiré in moiré topography and deflectometry

The optical logic-operated moiré is a new method to extract a specific moiré pattern. It has the capabilities of eliminating original carrier frequencies, increasing the contrast, and narrowing the fringes. We introduce its applications in moiré topography and deflectometry and also present the expe...

Description
Summary:The optical logic-operated moiré is a new method to extract a specific moiré pattern. It has the capabilities of eliminating original carrier frequencies, increasing the contrast, and narrowing the fringes. We introduce its applications in moiré topography and deflectometry and also present the experimental results.
