Abstract
This paper discusses apparatus for measuring the characteristics of the residual birefringence of large optical crystals of fluorite by the method of crossed polarizing sheets. A mathematical model of the proposed method is presented. The point-spread function, which describes the influence of birefringence on the image quality, is analyzed.
