Figure Lengend Snippet: a Unique visual strategy of Xenos peckii . The retinae of Xenos peckii are spherically arranged on a curved surface to achieve precise visual detection across a wide FOV via multi-angle chunk sampling. b Comparison between a conventional MLA camera and the SOEMLA camera. Conventional microlenses experience severe field curvature and astigmatism, along with a narrow FOV due to low disparities between optical units. In contrast, the SOEMLA camera, inspired by Xenos peckii , utilizes spatially offset-coupled apertures (SOAs) and ellipsoidal microlenses on a single planar CMOS image sensor. The SOAs with variable spatial offsets between upper and lower apertures effectively capture direction-specific partial images while minimizing field curvature. Ellipsoidal microlenses, integrated onto the lower apertures, form astigmatism-free PSFs across a wide FOV on the CMOS sensor.

Figure Lengend Snippet: a Experimental setup for capturing a large-area microfluidic chip (WD = 20 mm). Comparison of captured images between b the SOEMLA camera (FOV: 65 mm × 40 mm) and c a spherical MLA camera (FOV: 40 mm × 40 mm). Unlike the spherical MLA camera, the SOEMLA camera achieves uniform illumination and high contrast across the entire wide FOV. Scale bar: 5 mm. d Line intensity profiles corresponding to b and c. The reconstructed image from the SOEMLA camera clearly resolves microchannel structures with widths of 300 μm and 70 μm. e Experimental setup for capturing a full-scale adult oral phantom (WD = 30 mm). f Reconstructed images of maxillary and mandibular dentitions, labeled according to the ISO 3950 format. The SOEMLA camera allows for full-dentition imaging in a single acquisition within the confined oral cavity. g Enlarged views of the central incisors (teeth 11 and 21) alongside a commercial digital camera image. The intensity profile of the reconstructed image precisely reflects anatomical features such as the interincisal gap and marginal ridges. h Comparative images of a molar (tooth 46) using the spherical MLA camera, the commercial wide-angle camera, and the SOEMLA camera at a short WD. The SOEMLA camera demonstrates superior spatial resolution with clear structural boundaries. i Experimental setup for wearable facial imaging with an adjustable camera mount attached to an eyeglass frame. Scale bar: 20 mm. j Simultaneous imaging of both eyes under two distinct gaze directions at a WD of 25 mm. High-resolution capture at large angles provides reliable pupil identification for gaze tracking. k Reconstructed facial images at a WD of 50 mm under different expressions. The SOEMLA camera achieves effective full-face capture of dynamic facial features. Colored dots indicate facial landmarks.

Article Snippet: Over the years, various polar-orbiting satellite sensors, such as the AVHRR (Advanced Very High Resolution Radiometer), TOMS (Total Ozone Mapping Spectrometer), ATSR (Along Track Scanning Radiometer) sensors (including AATSR), the MODIS (MODerate-resolution Imaging Spectroradiometer) sensor on Terra , the MISR (Multi-angle Imaging Spectro Radio meter), POLDER (Polarization and Directionality of the Earth’s Reflectances), SeaWiFS (Sea-viewing Wide Field-of-view Sensor), MERIS (Medium Resolution Imaging Spectrometer), and the multi-angle polarimetric imager DPC (Directional Polarimetric Camera), China’s Gaofen-5 (GF-5) satellite , have been deployed to monitor aerosol products and atmospheric conditions.
