Plenary Session

Katie Bouman

California Institute of Technology, USA

Capturing the First Picture of a Black Hole and Beyond

This talk will present the methods and procedures used to produce the first image of a black hole from the Event Horizon Telescope, as well as discuss future developments. It had been theorized for decades that a black hole would leave a "shadow" on a background of hot gas. Taking a picture of this black hole shadow would help to address a number of important scientific questions, both on the nature of black holes and the validity of general relativity. Unfortunately, due to its small size, traditional imaging approaches require an Earth-sized radio telescope. In this talk, I discuss techniques the Event Horizon Telescope Collaboration has developed to photograph a black hole using the Event Horizon Telescope, a network of telescopes scattered across the globe. Imaging a black hole’s structure with this computational telescope required us to reconstruct images from sparse measurements, heavily corrupted by atmospheric error. This talk will summarize how the data from the 2017 observations were calibrated and imaged, and explain some of the challenges that arise with a heterogeneous telescope array like the EHT. The talk will also discuss future developments, including how we are developing machine learning methods to help design future telescope arrays.

About the Speaker

Katie Bouman is an assistant professor in the Computing and Mathematical Sciences Department at the California Institute of Technology. Before joining Caltech, she was a postdoctoral fellow in the Harvard-Smithsonian Center for Astrophysics. She received her Ph.D. in the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT in EECS. Before coming to MIT, she received her bachelor's degree in Electrical Engineering from the University of Michigan. The focus of her research is on using emerging computational methods to push the boundaries of interdisciplinary imaging.

Defining the Digital Camera

Conventionally “the camera” is well defined, it consists of a lens to form an image and a sensor to measure the image. In the modern camera, however, the image is formed computationally rather than by the lens. The camera consists of a variety of sensor resources, potentially including lens and sensor arrays with various forms of active illumination and 3D sensing. Camera designers must select these resources within size, weight, cost and power budgets to maximize the quality of computed media. While this approach creates design challenges, it also enables 100x increases pixel count per unit volume, 100x decreases in operational power per pixel and dramatic improvements spatial, spectral, temporal and range resolution. This talk reviews design strategies for heterogeneous sensor array cameras and analyzes system performance for various recent designs.

About the Speaker

David J. Brady is the Fitzpatrick Professor of Photonics at Duke University. In 2012, Professor Brady led the team that built the world’s first terrestrial gigapixel camera. He subsequently founded Aqueti, Inc., which manufactures array cameras. Brady has also worked on numerous applications of compressive measurement and computational imaging, in 2013 he was awarded the SPIE Denis Gabor Award for the development of compressive holography. His recent work focuses on the use of compressive measurement and artificial intelligence to improve data quality and quantity in parallel cameras; focusing on the ultimate goal of handheld gigapixel cameras. Brady is a fellow of OSA, SPIE and IEEE.
