In recent years, the introduction of modern computer vision algorithms has led to new and exciting developments in imaging sciences, such as lidar 3d mapping for autonomous driving or advanced pose estimation for human-robot interaction. In light of the seemingly limitless opportunities of these developments, the knowledge about fundamental limits has become even more important: By knowing that our imaging device already operates at the physical limit (e.g., of resolution), we can avoid unnecessary investments in better hardware, such as faster detectors, better optics, or cameras with higher pixel resolution. Moreover, limits often appear as uncertainty products, making it possible to optimize our measurement towards a specific quantity (e.g., speed) by trading in information less critical for the respective application. Although the imaging device is essential in this optimization, the central role is assumed by the illumination, which serves as encoder of the desired information.

In this talk, I will discuss the virtue of limits and merit of illumination modalities in computational 3D imaging systems using examples of my recent research. Among other projects, I will introduce a novel method to image hidden objects through scattering media or around corners and the ‘single-shot 3D video camera’ - a highly precise 3D sensor for the dense measurement of fast macroscopic live scenes.
