Abstract
A multipoint diffraction strain sensor (MDSS) in moire interferometer was developed earlier as direct approach for measuring strain of a macro-sized object. Recently a MDSS based on a micro-moire interferometer was proposed for measuring strain for a micro-sized object in wholefield with unique features, one of which is variable sensitivity and measurement range. The technique is now extended to measure both tilt and non-uniform strain of a material.
