Some of our research interests and current work areas are:

  • phase-only 2D/3D holography and spatial light modulation;
  • large area multi-stable reflective colour displays;
  • high frequency low loss tunable dielectrics and phase element applications;
  • liquid crystal based material systems and nano composites;
  • adaptable nano-photonic structures;
  • novel devices for electro-magnetic sensing;
  • phase-only liquid crystal over silicon (LCOS) modules;
  • smart chips and two-way optics;
  • optical system design for display, measurement and telecoms applications;
  • development of electronic driver and software interfaces for demonstrators.
  • hybrid propulsion systems

Hybrid propulsion


The first test flight of a manned electric-petrol hybrid aircraft took place in September 2010 at Sywell Aerodrome, UK. The propulsion system was designed and built by Dr Paul Robertson and comprises a 12kW custom-wound brushless DC outrunner motor in parallel with a 76cc 4-stroke internal combustion engine producing 2.8kW, replacing the standard 2-stroke engine on an Alatus motorglider. The electric motor is driven by a custom built controller, powered by 16 LiPo cells of 40 Ah capacity, giving an electrical energy storage capacity of 2.4 kWh. This is an experimental aircraft which will be used as a test-bed to evaluate and refine the hybrid technolgy - including the use of alternative fuels. A YoutTube movie of the flight can be seen by following this link.
