Latest Developments in Colour Holography

by Daniel Blackmore

The focus of this presentation is to highlight the different ways in which artists and scientist create depth within their holograms and will explore three main examples of how this can be done. The first is using mirrors to create depth in holograms this is a very technical method which requires allot of aligning as interference can occur when using mirrors in holograms. The element of depth is achieved using a method of controlling the point at which the object beam intersects the reference beam, this is similar to the double beam. The double beam holography method, uses a reference beam and an object beam which allows for the creation of more depth within holographic spaces by adjusting the position of where the object and reference beam intersect, leading to a deeper positioned image. A simpler approach can however, if fined tuned, can give good results, simply by moving the plate further away from the object being recorded, can give the illusion of the object appearing deep in the holographic space. Finally, and by far the most astonishing way of creating holographic space is by selecting the appropriate object, sometimes the wonder of holographic recording itself can be enough to demonstrate this principle using a long object such as a pitch fork, as seen in the image below can be enough to create a deep image.

Oliver Peacock

I was first introduced to holography during the second year of my Physics undergraduate course, but my interest in the field heightened during my third year where I was tasked with recording an interference pattern from a Michelson Interferometer onto a holographic plate. This led to an offer at De Montfort University where I am developing new techniques which promise to maximise the recording of deep spatial transmission holograms, as well as experimenting with lenses in holograms. I am also working on broadening out understanding of holographic principles through an optical system known as Schlieren, a visualisation tool for air flow amongst other things

Dynamic and Full-Color Projective Imaging Technology

by Dr. Weiwei Zhang

Two novel projective imaging technologies are introduced in this article. The projective images can be easily observed by public in reflection,or transmittion, or projection.The light sources can be mobile phone flash. One can observe not only the achromatic images, but also full-color ones, and even vivid dynamic amination. These technologies are based on the combination and coordination of reflection, interference and diffraction. The accurate control of microstructure origination and metallization process guarantees the high-level security feature. Coordinated with other first level security features such as holograph, demetallization and surface plasmon resonance, the novel projective imagine technologies can provide integrated authentication of high value documentation, and exhibit promising future in security threads, stripes and patches

Dr. Weiwei Zhang

Dr. Weiwei Zhang graduated from School of Physics in Beihang University, China. He joined Zhongchao Special Security Technology Co., Ltd. in 2010. He specializes in research and development of optical security technology, especially in optical security effects design, micro structure origination and optical thin film coating. He also participates in design and development of security products.

Latest Developments in the HIR

by Paul Dunn

The IHMA (International Hologram Manufacturers Association) was conceived in 1993 to represent and promote the interests of hologram manufacturers and the hologram industry worldwide. One of the first projects and services to our members, was the design and introduction of the Hologram Image Register (HIR), a highly secure register of holographic images. The objective being to safeguard hologram copyright as a foundation to their use in authentication and security printing.
In 2014 the registration process was changed to a digital system with secure access to registration via an online portal managed by the Counterfeit Intelligence Bureau (CIB), who have managed the Image Register from its first inception on behalf of the IHMA.
Today this unique register has evolved and is perceived as the ‘jewel in the crown’ of the IHMA services. It is also now an integral part of compliance with the ISO 14298 standard. However, as the industry evolves, we need to ensure the HIR also evolves to keep pace to meet the needs of the IHMA members. New HIR updates will be introduced in the coming weeks and I will review the driving influences and describe the changes themselves and the value they will bring to IHMA members old and new.

Paul Dunn

Paul Dunn received a PhD in Physics from the University of Birmingham in 1979 and was awarded a Nato Research Scholarship based in the USA at the Institute of Optics, University of Rochester, NY. Here he spent four years as a lecturer and researching into image processing and also taught Physics and Mathematics at the Rochester Institute of Technology.

In 1983 he returned to the UK to work as a consultant before joining Third Dimension as Technical Director, developing holograms and optical technologies for a variety of applications.

Paul joined Applied Holographics in 1988 developing the team and facilities forming the basis of all origination and optical developments. In 2000, Applied acquired OpSec Security and Paul developed his role as Technology Director as the company evolved and his role focussed more towards R&D.

He has been involved in the Optical Security industry for over 30 years with an array of experience in teaching and technology development and holds an MBA. He has maintained a particular focus on the development of technologies for new optical features, origination technologies, product applications and materials for which he holds many patents and over 40 publications. In 2018 he received the Brian Monaghan Award for Business Innovation.

Paul is currently Director of Technology Innovation at OpSec Security Ltd and is the Chairman of the International Hologram Manufacturers Association (IHMA).
