Abstract

See full text

An interferometric tracking device includes image dividers arranged to form an optical cascade, with one of the image dividers being an incident image divider for the optical cascade and one or more of the image dividers being one or more exit image dividers for the optical cascade. Each of the image dividers splits incident light into a plurality of non-parallel orthogonally polarized beams, the beams from the incident image divider cascading through the other image dividers in the cascade. One of a plurality of shearing interferometers is optically coupled between optically adjacent image dividers in the cascade. The orthogonally polarized beams from the one or more exit image dividers are imaged onto one or more focal plane arrays.
