| Popis: | In this paper, a physical model of full-field time-domain optical coherence tomography (FF-TD OCT), which focuses the requirements of measuring inner textures of flexible layered samples in industrial applications, is developed and validated by reference measurements. Both the operating principle and the overall design of a FF-TD OCT correspond to that of classical white light interferometry (WLI), commonly used for the measurement of areal micro-topographies. The presented model accounts for optical and geometrical properties of the system, multiple scattering of light in turbid media and interference of partially coherent light. Applying this model, virtual measurements are used to exemplarily investigate the extent to which the principles of classical WLI can be directly transferred to obtain layer thickness measurements by simulating the use of a simple low-cost WLI system as OCT. Results indicate that a currently existing instrument setup can only be used as OCT to a very limited extent but not in general due to its initial design as a WLI.
