Workshop: Synthetic Apertures in Computational Imaging

IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP) is the world’s largest and most comprehensive technical conference focused on signal processing and its applications. It offers a comprehensive technical program presenting all the latest development in research and technology in the industry that attracts thousands of professionals annually.

This workshop is organised by the IEEE Technical Working Group on Synthetic Apertures (https://signalprocessingsociety.org/community-involvement/synthetic-aperture-technical-working-group/synthetic-aperture-technical) and provides a significant opportunity to raise awareness of the importance of synthetic apertures across a broad range of technologies. We provide a panoramic view of the field of Phase Retrieval, spanning critical Synthetic Aperture applications such as optics, microscopy, and radar. The scope and depth of synthetic aperture applications is so substantial that it warrants a dedicated workshop to cover it in sufficient detail. It is focused on the signal processing aspects of synthetic apertures and therefore complements it. 

Topics of Interests

The workshop will aim to attract speakers in several key areas of Synthetic Apertures, including those outside the main specialties of signal processing. Specific topics of interest include, but are not limited to: 

• Optical imaging: Optical imaging with synthetic aperture combines multiple optical images captured from different viewpoints to create high-resolution, detailed images, often used in fields like remote sensing, biomedical imaging, and surveillance.  

• Beamforming in Ultrasound Imaging: Processes signals from multiple spatially separated elements to construct high-resolution images, applied in medical imaging, and non-destructive testing. 

• Ultrasound Imaging: Synthesizes data from multiple acoustic signals to enhance image resolution and depth, widely used in medical diagnostics, material inspection, underwater imaging, and geophysical exploration. 

• Phase Retrieval: Reconstructs phase information from intensity-only measurements to produce high-resolution images, used in fields like X-ray crystallography, electron microscopy, optical imaging, and astronomy. 

• Synthetic Aperture Radar: Uses motion to simulate a large antenna, capturing high-resolution images of the Earth's surface, commonly applied in remote sensing, environmental monitoring, military surveillance, and disaster management. 

• Synthetic Aperture in Optics: Combines data from multiple images or light wavefronts to enhance resolution beyond a single aperture's limit, with applications in microscopy, astronomy, remote sensing, and holography.
