Abstract

Obtaining and analysing a depth-resolved signal along an electromagnetic radiation path comprises using a delivery section arranged to emit polarised electromagnetic radiation and a calibration section 170 comprising at least three reference surfaces 171a, 171b, 172a, 172b arranged in a path of the radiation emitted by the delivery section. A signal associated with a sample 150, also in the radiation path, and the calibration section is detected at a polarisation sensitive radiation detection section. Based on the received data, at least one of an absolute orientation of a fast-axis of the sample, a completely specified Jones matrix for the sample, or a completely specified Jones matrix for the electromagnetic radiation path between the calibration section and the detection section, is determined. The reference surfaces may be the faces of retarders such as quarter wave plates 171, 172 and form part of a polarisation-sensitive optical coherence tomography (PS-OCT) device or similar interferometer device.
