The use of optics in everyday life is ubiquitous. For example, internet is used all the time without realizing that ultimately these are light pulses that carry the information across the world on a fibre optic network. Even the foundations for contemporary television display technologies like LCDs, LEDs and three-dimensional TVs were laid by optical physicists. Dr. Mumtaz Ali Sheikh focuses on using light for a large variety of similar applications. He has been involved in the development of extreme temperature optical sensors for use in gas turbines at temperatures where ordinary industrial thermocouples break down very quickly. His current projects include the development of a super-resolution confocal microscope using disordered media. He is also interested in the areas of optical communication, singular optics and 3D laser ranging.
