Maria, M. (author), d'Hont, Lieve (author), Anisimov, A. (author), Stols-Witlox, Maartje (author), Groves, R.M. (author)In this study, we describe a method for measuring the spectral reflectance of a paint layer at both the surface and in the volume of the paint layers. We first present a fringes model which illustrates the possibilities for spectral reconstruction using a Short-Time-Fourier-Transform algorithm. We investigate the remaing percentage errors and...conference paper 2021

Maria, M. (author), Anisimov, A. (author), Stols-Witlox, Maartje (author), Groves, R.M. (author)In this study we investigate the possibility of spectra stitching in the context of Spectral Domain - Optical Coherence Tomography (SD-OCT). The aim is to reach a high axial resolution while keeping sampling issues to a low level (slow decay in depth) but still operating with the fastest camera line rate available. The paper focuses mainly on...conference paper 2020

Maria, M. (author), Anisimov, A. (author), Stols-Witlox, Maartje (author), Groves, R.M. (author)In this study, we compare the hyperspectral imaging capabilities of a custom-built visible light OCT with those of a commercial grade hyperspectral camera. Using the Short-Time-Fourier-Transform algorithm on the OCT signal, we estimate the variation in the surface spectral response from two paint pigments. Our study aims at comparing the...conference paper 2020
