The optical coherence tomography is an optical measurement technique used for investigation of wide range of scattering or semitransparent materials. The optical coherence tomography enables surface and subsurface examination of different types of materials to be performed in non-contact and non-destructive way. Our research have been concentrated on optical coherence tomography systems with polarization sensitive analysis. Such a combination of optical measurements methods improves optical coherence tomography visualization contrast and also delivers some extra information about investigated devices. However, applying polarization sensitive analysis is associated with problems related to the use of ultra broadband optical sources. We have managed studies on the improvement of signal processing method. According to obtained results the problem of signal processing method in polarization sensitive optical coherence tomography can be solved by the use of the spectroscopic analysis. In this paper we present a brief discussion about the polarization sensitive optical coherence tomography measurements supported by spectroscopic analysis of backscattered light from investigated device.

Optical low-coherence tomography is a measurement technique for non-contact and non-destructive investigation of materials inner structure. Nowadays, this method is highly applied in medical treatment especially in dermatology and ophthalmology. During our research we have developed an optical low-coherence tomography system with polarization state analysis for structure examination of a broad range of technical materials. In this paper we present our recent measurements including polarization sensitive analysis. Those measurements were taken for semitransparent and highly scattering materials like polymer layers and polymer optical retarders, anticorrosion protective coatings or abrasive paper. We proved that with the aid of developed polarization sensitive optical coherence tomography system it is possible to investigate birefringence principles of materials as well as to improve visualization contrast of cross-sectional images.
