Joint feature issue in Optics Express, Applied Optics, and Biomedical Optics Express: Computational Optical Sensing and Imaging 2025.

This joint feature issue of Optics Express, Applied Optics, and Biomedical Optics Express showcases recent work from the Computational Optical Sensing and Imaging community. The issue reflects the continuing expansion of computational optical sensing and imaging, where optical design, detection, calibration, physical optical system modeling, signal processing, and machine learning to acquire task-relevant information. The selected papers span computational microscopy and biomedical imaging, adaptive optics, wavefront sensing, holography, phase retrieval, single-pixel and ghost imaging, hyperspectral and polarization imaging, non-line-of-sight imaging, LiDAR, photon-efficient sensing, optical-system co-design, and emerging applications in medicine, remote sensing, manufacturing, and environmental metrology. Together, these contributions illustrate how computationally co-designed optical systems are moving from algorithmic demonstrations toward robust, application-specific imaging and sensing platforms.
