Paper Abstract

We present an analysis of the Savart interferoineter calculating the interference fringes produced by the superposition of the wavefronts from the geometrical images formed by the birefringent element. 1. INTERFERENCE FRINGES FROM THE SAVART PLATE In this work we propose a procedure for analyzing the Savart interferometer including the zone of the field that is not used as a working zone. Using the ray tracing metho the images formed by a plane parallel birefringent plate were obtained . These are: an ordinary image without first order aberrations and an extraordinary one astigmatic to firs: order. In the Savart plate the two images that are formed by the rays that are extraordinary in the one plate an ordinary in the other are astigmatic. The rays that are ordinary in both plates give a point image without first order aberrations and those that are extraordinary in both plates do not exhibit first order aberrations either because the astigmatism is coinpensed. To obtain the interference fringes the forms of the wavefronts corresponding to the images are calculated and from these the corresponding phase shifts are found. The figure shows the pattern generated by the interference between the following images: OE (ordinary in the first and extraordinary in the second plate) with EO giving rise to the system that is sharp in the center of the field 00 with OE and EO which give fringes
