Researchers propose using dynamic scattering to control speckle noise and aberrations in optical coherence tomography (OCT). Speckle arises from spatially coherent light; removing coherence eliminates speckle but also sacrifices the interferometric imaging capability that OCT relies on. The method strikes a balance between the two to improve detail in high-resolution imaging.
A team led by the University of Central Florida (UCF) will receive a five-year, $19.2 million grant from the US Army Research Office to study light propagation and control in complex dynamic environments. The project, led by Guifang Li, will explore weak backscattering coherent measurement, inverse methods, AI analysis and multi-plane light conversion, with the goal of measuring and rapidly correcting light field distortions when remote sensors or beacons cannot be placed. Potential applications include directed-energy systems, biological tissue imaging, laser medicine, remote sensing and free-space optical communications.

Google has outlined the development of the Pixel camera's Add Me feature, which combines two photos taken sequentially of the same scene so that the photographer can also appear in the group shot. The second photographer sees an augmented reality overlay of the first photo to align the composition. The feature relies on multiple machine learning models running locally on the TPU of the Tensor G4 chip. Add Me launched with the Pixel 9 series.
