1. An arrangement for use in performing spatial offset analysis of a medium, wherein the arrangement comprises:
- a birefringent component including a birefringent material, the birefringent component comprising a first side adjacent a detector and a second side adjacent the medium, the birefringent component configured to first manipulate a beam of primary radiation of a first polarization that is incident on the first side, the first manipulation directing the beam of primary radiation to a first location of the medium, the birefringent component further configured to second manipulate at least part of a beam of secondary radiation of a second polarization incident on the second side from a second location of the medium, the secondary radiation based on irradiation of the medium by the primary radiation, the second manipulation directing the at least part of the beam of secondary radiation to the detector, the second location being at least partially different from the first location, wherein the effect of the first manipulation is different from the effect of the second manipulation due to the first polarization being different from the second polarization.

Abstract
An arrangement having a birefringent component is provided for use in spatial offset measurements and analysis systems. The birefringent optical arrangement provides different directional control of the excitation signal relative to the emission signal, so that offset between an excitation and emission location on a sample can be controlled for both or only one of the excitation signal relative to the emission signal.

29. A method for performing spatial offset detection, the method comprising:
-
manipulating at a birefringent component a beam of primary radiation that passes through birefringent material of the birefringent component, the manipulation directing the beam of primary radiation to a medium at a first location, the primary radiation comprising a first polarization, the birefringent component comprising birefringent material; and manipulating at the birefringent component at least part of a beam of secondary radiation having a second polarization that is emitted from a second location of the medium, the emission based on irradiation of the medium by the primary radiation, the manipulation of the at least part of the beam of secondary radiation directing the at least part of the beam of secondary radiation to a detector, the second location being at least partially different from the first location, wherein the effect of the manipulation of the beam of primary radiation is different from the effect of the manipulation of the at least part of the beam of secondary radiation due to the first polarization being different from the second polarization. - View Dependent Claims (30, 31, 32, 33, 34)
