Full bandwidth dynamic coarse integral holographic displays.


An efficient method to implement the coarse integral holographic (CIH) concept for a dynamic CIH displays is to scan the information generated from a space light modulator (SLM) of a low spatial bandwidth product (SBP) but high bandwidth to form the hologram array for the integral optics. Previously, just over half of the SLMs bandwidth was utilized previously due to the fact that the galvanometer scanner in use could not tile all the holograms which the SLM is capable to produce, resulting in the loss of nearly half of the field of view (FOV). We propose a full bandwidth dynamic CIH display using a large resonant scanner in conjunction with a hybrid raster scanner, which can utilize the full bandwidth of the spatial light modulator and double the horizontal FOV. This approach can be used for future scalable and tileable CIH display systems.


Introduction of CPDS

Centre for Photonic Devices and Sensors (CPDS) is in the Photonics area of the Electrical Engineering Division, with a research focus embracing photonic and sensing devices, functional materials and their integration at system level.

We aim to address future societal needs with new system functionalities through invention of novel device architectures based on in-depth understanding of basic material properties.

There is a wide range of activities within the group, including phase-only holography and its applications, high brightness multi-stable colour reflective displays, tuneable dielectric materials and devices for radio frequencies, liquid crystal on silicon (LCOS) device development, and novel sensors.

As well as conducting highly focused studies, we also specialise in the development of demonstrators for business exploitation and commercialisation. This is facilitated by multi-disciplinary expertise within the group and by our highly experienced team approach. Some of the outcomes from the group have been successfully transferred to our industrial collaborators for production.
