Paper Abstract
Moiré pattern, produced by the overlapping of two radially sheared beams emerging from two longitudinally shifted
focal points of a birefringent lens has been experimentally demonstrated. Coherent and incoherent Moiré patterns are
generated with and without analyzer. Birefringent samples like mica sheets with opposite crystal axis to that of the
birefringent lens modulate the Moiré pattern. Mica sheet of different thicknesses have been used to demonstrate the
effect of thickness on phase retardation, hence on fringe pattern. Experimentally birefringence has been calculated by
fringe analysis and compared with theoretically simulated birefringence.
