title: Reduced sensitivity phase object analysis by moiré techniques.
abstract: Projected interference fringes are altered if a phase object is placed in their way. Comparing the original fringe pattern with the new one reveals useful information about the object and the incident light waves. The system is analyzed theoretically, and some possible applications are indicated through experimental verification of the predicted effects.
