Sebastian Bauer, Postdoctoral Student at the University of Wisconsin – Madison, presents the “Introduction to Single-Photon Avalanche Diodes—A New Type of Imager for Computer Vision” tutorial at the May 2021 Embedded Vision Summit.
The single-photon avalanche diode (SPAD) is an emerging image sensing technology with unique capabilities relevant to computer vision applications. Originally designed for imaging in low-light conditions, the ultra-high time resolution of SPADs also helps to achieve extremely high dynamic range, motion blur-free images and even seeing around corners. The use of SPADs in recent iPhone models has spurred increased interest in the use of SPADs in commercial products.
In this talk, Bauer introduces SPAD-based imagers, explains how they work, presents their fundamental capabilities, and identifies their key strengths and weaknesses relative to conventional image sensors. He also shows how they can be used in a variety of applications.
