Digital holographic applications for mobile devices

Final Activity Report Summary - HOLOMOBILE (Digital holographic applications for mobile devices)

Digital holography is an emerging technology for the sensing and display of real-world three-dimensional (3D) objects and scenes. The longstanding foundations of the subject, classical holography, are well researched and well understood. However, with software representation of a hologram (a digital hologram) comes new possibilities (such as image processing of the 3D data) and new unsolved challenges (such as how to extract 3D data from the hologram).

This project concerned the initial stages of a long term effort to combine digital holography 3D imaging technologies with mobile devices, thus opening up a range of novel applications. The results are at several levels, from the theoretical through algorithm and prototype design, to application evaluation. Specifically, hologram-capture architectures have been designed and tested that would be suitable for the restricted footprint associated with mobile device implementation. These architectures necessarily incorporate trade-offs that limit functionality and quality. As such, novel and specialised algorithms are required to compensate and make the captured data usable, and to interpret the 3D data within. Optical processing and parallel processing of the 3D data was considered to reduce the sequential computational overhead. One major focus of the project concerned content protection and digital rights management for the sensed 3D objects. Ultimately, this project led to the first reported techniques for porting 3D holographic information to conventional mobile devices and evaluating its 3D properties. Much of the gained knowledge is exploited as part of a three-year eight-partner European Commission funded collaborative project called Real 3D that has evolved from this project.
