Schematic setup of the Michelson interferometer consisting of a (point) light source S 0, mirrors Ma and Mb , a beamsplitter (BS), and a compensator plate (CP).
Different optical paths of the waves reflected (left) and transmitted (right) by the beamsplitter in the Michelson interferometer without the compensator plate.
A homocentric pencil of rays from light source S 0 becomes astigmatic as it passes through a glass plate of thickness d. There are two different focal points for rays in the plane of incidence (F 1) and rays normal to the plane of incidence (F 2).
Displacements of the foci of the refracted ray by the air-glass interface and the corresponding principal centers of curvature (F 1 and F 2) of the waves.
Comparison of the displacements of the centers of curvature of the wave-fronts reflected (left) and transmitted (right) by the beamsplitter in a Michelson interferometer without the compensator plate.
Optical path length differences (OPD) on the screen with mirror Ma at different locations, and the corresponding interference fringes.
Illustration of the derivation of the position of the primary focus F 1.
