| Abstract: | A theoretical investigation of the signal processing by ESPI is presented. Both electronic and optical noise are taken care of, and the optimum of ESPI with regard to the reference/object-ratio is found. In the limit of small electronic noise contributions this optimum is reached when the noise on the reference beam is equal to the noise on the object beam. |
