Measurement of selected characteristics of low-coherence optical signal sources for optical coherence tomography

摘要

Optical Coherence Tomography (OCT) is a new type of an imaging technique of the internal microstructure of the material. Among several detection techniques which can be used to implement OCT, Optical Low-Coherence Reflectometry (OLCR) is the most common and the most promising one. OLCR uses a broadband source, which parameters: the spectral characteristics and the noise property, determine metrological abilities of the designed OCT system. Authors measured the power spectral density of the intensity noise, as well as the spectral characteristic of various broadband sources: Obtained results has been used to determine metrological properties of the design OCT system.
