Arrangements, systems and methods capable of providing spectral-domain polarization-sensitive optical coherence tomography
First Claim
1. An apparatus for separating an electromagnetic radiation, comprising:
- a first arrangement configured to separate the electromagnetic radiation into at least one first portion and at least one second portion according to at least one polarization and at least one wave-length of the electromagnetic radiation; and
a second arrangement configured to simultaneously detect the separated first and second portions.

Abstract
Systems, arrangements and methods for separating an electromagnetic radiation and obtaining information for a sample using an electromagnetic radiation are provided. In particular, the electromagnetic radiation can be separated into at least one first portion and at least one second portion according to at least one polarization and at least one wave-length of the electromagnetic radiation. The first and second separated portions may be simultaneously detected. Further, a first radiation can be obtained from the sample and a second radiation may be obtained from a reference, and the first and second radiations may be combined to form a further radiation, with the first and second radiations being associated with the electro-magnetic radiation. The information is provided as a function of first and second portions of the further radiations that have been previously separated and can be analyzed to extract birefringent information characterizing the sample.
