Subject: The Modern Imaging Paradigm: There is Plenty of Room in the Middle

Every modern imaging system is comprised of optical, sensing, and computational modules that work in an integrated fashion to perform a dedicated imaging task as efficiently as possible. This new paradigm of imaging, called integrated or computational imaging, has enabled spectacular advances in probing remote objects and environments. I will illustrate this paradigm with an important application, namely Lord Rayleigh's classic resolution limit on the separability of two closely-spaced point sources from their images. I will show why such a limit has become a mere relic, one that has been usurped spectacularly by modern advances in image processing, new imaging methodologies, and ingenious work-arounds. Yet the best pair resolution that one can hope to achieve seems to be fundamentally limited by the number of signal photons available when making direct image measurements on the source pair. I will discuss a new approach of pair super-resolution that can qualitatively improve upon this seemingly insuperable photon limit, with quantum estimation theory revealing the ultimate bound on this phenomenon. Rather surprisingly, as I will also show, one can attain this quantum bound in certain limits in all three spatial dimensions with purely classical measurements that are not image based, but rather utilize coherent projections of the optical wave front. Phase does matter, even when imaging incoherent objects.

7:00 pm:
Kaufmanis Public Lecture in McNamara Alumni Center
Speaker: Victoria Kaspi, McGill University
Subject: Astronomy's Newest Extragalactic Mystery: Fast Radio Bursts!

In 2007, astronomers discovered a new mysterious cosmic phenomenon: Fast Radio Bursts. These events consist of short, intense blasts of radio waves arriving from far outside our Milky Way galaxy. Their origin is unknown, however Fast Radio Bursts appear ubiquitous in our Universe, with roughly 1000 arriving every day over the full sky. I will discuss the Fast Radio Burst mystery and what is presently known about it, and describe a revolutionary new radio telescope being built in Canada that will soon enable astronomers worldwide to make major progress in our understanding of the FRB puzzle.
