Abstract
Polarization aberrations are variations of the instrumental polarization associated with different ray paths through an optical system. The polarization aberrations of an overhead projector are easily observed with two large sheets of Polaroid. The form of these polarization aberrations are described as functions of object and pupil coordinate and are related to the polarizing properties of the lenses and mirrors. These polarization aberrations do not adversely affect the performance of an overhead projector, but they do provide an easy and effective demonstration of the concepts of instrumental polarization. Subject terms: polarization; polarization aberration; mirrors; retardance; diattenuation; Jones calculus.
