Long Teng is a visiting PhD student from School of Physics, Nanjing University, P. R. China. He received his Bachelor degree in Materials Science and Engineering from Southeast University in 2010. He spent a semester studying at ENSAM, Paris Tech, France to accomplish his bachelor degree dissertation related to X-ray diffraction in 2010. His research at Nanjing University was focused on III-V semiconduct materials and devices. Since September 2012 he has been studying in the Photonics & Sensors Group, Electrical Engineering Division, Department of Engineering at the University of Cambridge. His current research interests include: Applications of liquid crystal on silicon (LCOS), Semiconduct materials and devices
BIREFRINGENCE FLAME This microscopic photo shows the birefringence colour on a Liquid Crystal on Silicon (LCoS) device. Birefringence is when light passing through a crystal is split into two different waves of light, resulting in the beautiful colours you can see in this image. A LCoS device is similar to an LCD (Liquid Crystal TV and video Displays), except an LCoS is also reflective, resulting in a very high resolution. This image demonstrates how the birefringence properties of crystals can be used to refract light, creating a colourful and sharp image on our TV screens, making the fake tans on TOWIE glow more than ever before...
