Abstract

Manufacturers of optical glass strive to make a product that is homogeneous, isotropic, and free of any bubbles or mechanical strain. Glass used in forming images is very good, but the process of mixing the constituent materials, and melting them into a glass is limited. As uniform as the mixtures are, they are not perfect, and the effects can be seen anytime light must propagate through several centimeters of glass. One method for measuring the three dimensional inhomogeneities in a piece of glass will be shown. Interferometry and computed tomography will be used to map the bulk refractive index variations. Having three dimensional information on the refractive index is the first step in compensating for errors in an imaging system.
