Paper Abstract

The purpose is to evaluate the effectiveness of a retroreflector when employed in a moiré deflectometric telescope. A moiré deflectometric telescope using a retroreflector is designed based on the standard moiré deflectometer combining a retroreflector as invented by the authors. A density variation in a piece of glass (phase object) is considered. Moiré deflectograms are obtained using the standard setup for a moiré deflectometer as well as with the setup employing a retroreflector. The setup of a moiré deflectometric telescope and the newly designed moiré deflectometric telescope using a retroreflector are tested.
