An Insight into Holographic Sensors Research: Challenges and Applications
Hosted By: Holography and Diffractive Optics Technical Group
25 March 2022 12:00 - 13:00
Eastern Time (US & Canada) (UTC -05:00)Although holographic sensors for the detection of chemical and biological substances have been around for more than two decades, the thorough theoretical analysis of their properties has only started to emerge in recent years. There is a double benefit to understanding how to optimize the sensitivity of holographic structures in response to external stimuli – it can identify the best structures for use in sensors and can also teach us how to minimize this response when it is not needed. For example, this is particularly important when holographic optical elements are intended for use outdoors, where the temperature and humidity vary.
In this webinar hosted by the Holography and Diffractive Optics Technical Group, Izabela Naydenova will offer a brief introduction to the principles of operation of holographic sensors, followed by results from their theoretical modeling and optimization. There will be a discussion of the different approaches to the functionalization of holographic structures and the key challenges related to this aspect of their design. Holographic sensors for use in the detection of substances in liquid and gaseous samples will be discussed by introducing some practical examples.
