Holography for Wavefront Sensors & Vision

In this research domain we are focused on utilising holographic techniques to develop novel, useful wavefront sensors and to improve the diagnosis and treatment of eye conditions.

Currently we have a Science Foundation Ireland (SFI) funded project to develop a suite of Analog Holographic Wavefront Sensors (AHWFS) using Holographic Optical Elements (HOEs) - follow us https://twitter.com/Holowave_IEO. It will have benefits of rapidly outputting the identity and strength of aberrations present in a wavefront through optical processing. Leading to a low-cost, low-complexity, high-speed, repeatable WFS. This would have applications in areas as diverse as free space optical communications, astronomy, ophthalmology, adaptive optics and optical metrology.

Research is also underway to investigate the potential use of HOEs in the diagnosis and treatment of various eye conditions (such as amblyopia, diplopia, myopia, hyperopia and presbyopia). This is done by designing a custom interference pattern to be holographically recorded as a volume hologram in a thin (< 100µm), flexible, lightweight photopolymer material. This HOE can then be adhered to spectacles or another carrier substrate and offer bespoke treatment for the patients eye condition.
