Paper Abstract

Eastman Kodak Company has developed an automated method of measuring double pass optical retardation. The retardation of interest is caused by cover sheet or transparent substrate birefringence of completed optical disks. The method lends itself to producing continuous curves of double pass retardation measurements at a constant radius around a disk or along a line. It is inherently insensitive to the orientation of the optical axes of the sample. The theory, equipment and capabilities will be described.
