Name
Dr. Izabela Naydenova, Dr. Suzanne Martin
Research Centre (if applicable):
IEO (Industrial Engineering Optics)
The centre specialises in holographic and
interferometric techniques and has developed
novel technologies with applications in product
authentication, sensing, vibration measurement
and optical device fabrication. The Centre has been
in existence for nearly fifteen years and research is
carried out in well-equipped optical research
laboratories in DIT Kevin street and the FOCAS
Institute. Key areas of expertise include high
resolution photosensitive materials development,
interferometric systems for surface measurement
and holographic devices.

Title of the Project: Low-scattering Volume Holographic Material
Project Summary:
The Centre for Industrial and Engineering Optics (IEO), School of Physics, Dublin Institute of Technology
has a strong track record in development of holographic recording materials for applications in
holographic sensors, holographic devices and security holograms. Recently the IEO centre was involved
in the establishment of OPTRACE Ltd, a DIT spin-out company. The company is seeking to
commercialise individualized security holograms using a patented technology developed in IEO.
Based on previous experience in developing holographic photopolymers it is proposed to develop a
novel photopolymer material, characterised by low scatter and high refractive index modulation,
capable of recording volume holograms. Two main strategies will be adopted – use of different
monomers and use of nanoparticle dopants. The proposed approach allows for fine control over the
following features:





maximum refractive index modulation
spatial frequency range of performance
stability of the recorded hologram
sensitivity
scattering properties
Main features of the material will be self-processing, low scatter, high sensitivity and high dynamic
range.
