SIGGRAPH 2023 Course on
Computational Interferometric Imaging

teaser
Interferometric imaging techniques use illumination with different coherence properties to enable capabilities such as micrometer 3D imaging, femtosecond transient imaging, non-line-of-sight imaging, and imaging through scattering media.

Description

This course provides an overview of recent developments in computational interferometric imaging. We provide background on interferometric imaging and describe emerging technologies capable of unprecedented micrometer depth and femtosecond timing resolutions. We show applications on active and passive 3D imaging, transient imaging, non-line-of-sight imaging, and imaging through scattering media.
