Exit Pupil Patterns from Optical Disks

Abstract

The modulation of the irradiance in the exit pupil of an optical data storage scanning system is described by analyzing the behavior of scan-dependent interference fringes. These fringes are grouped into three independent irradiance components. The variation of the exit pupil irradiance pattern as a function of groove depth is discussed.
