We are pleased to announce a new, online edition of the NICAS colloquium on Thursday 24 November 2022 from 12.00 to 13.00 hrs. The colloquium will take place online through Microsoft Teams.
Throughout the year, NICAS organises a bi-weekly Colloquium consisting of two short research lectures. It provides researchers with the opportunity to present ideas for, updates on or results of their activities. The NICAS Colloquium allows people to stay informed on a regular basis about the latest developments and results of research and to exchange information and expertise.
The chair of this colloquium is Alessandra Marrocchesi (University of Amsterdam)
The presenters are:
► Mitra Almasian – Relating Structure and Color in Glass-containing Paints
(NICAS Small Project Grant)
Abstract:
In this NICAS small project grant project we investigated the influence of the addition of powdered-glass on morphology and visual appearance of cochineal and verdigris glazes. Therefore, we have created a range of reconstructions based on historic recipes, which were studies using conventional techniques: OCT, hyperspectral imaging and ranking light photography. Furthermore, we present a proof of principle combining depth-resolved spectroscopy and light-transport modelling in order to create virtual reconstructions. In the future, such simulated reconstructions can aid us to reveal the optical effects of adding colourless glass to paints as well as the influence of morphology and optical degradation on the optical response of paints.
Bio:
Mitra Almasian is a postdoctoral researcher at the Amsterdam UMC, University Medical Centers and a guest researcher at the Rijksmuseum. Her research focusses on the use of optical techniques for non-invasive imaging and diagnostics, with a main focus on OCT. She has a BSc in beta-gamma and a MSc in Physical Chemistry, both obtained at the University of Amsterdam. The topic of her PhD research, at the Biomedical Engineering and Physics department of the Amsterdam UMC, was the quantitative analysis of OCT signals and their medical application.
