Noise in Optical Measurements Workshop
Workshop Leader: Prof. Emanuel Istrate, Victoria College, University of Toronto
Thu, May 7: , 1:00-3:00pm, EM005 (Practical)
Title: Noise in Optical Measurements
Abstract: This workshop will explore the physical processes underlying noise in measurements, with a focus on optical measurements and the electronic circuits used to collect signals. An example calculation will illustrate how the magnitude of noise can be estimated and will be used to describe ways in which noise can be reduced. Finally, a brief introduction will be provided to the use of lock-in amplifiers to extract signals from noise. The practical session (on the second day) will give a brief introduction to free-space optical alignment techniques and demonstration of using lock-in amplifiers to collect very weak signals.
Bio: Emanuel Istrate received his Ph.D. in Photonics from the University of Toronto in 2005. As the Academic Program Coordinator of the Institute for Optical Sciences at U of T, he set up a number of courses and training programs in optics at all levels of the University. His current teaching at Victoria College includes courses on scientific creativity, science communication, and other social interactions of scientists. He also teaches a course covering the art and science of holography, and a course on film photography and analogy image manipulation in the darkroom. He has made contributions to lensless microscopy methods, entrepreneurship training programs and to collaborative projects with industry.
