    Xenos Inc soemla camera
    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 <t>SOEMLA</t> 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 <t>camera,</t> <t>inspired</t> by Xenos peckii , utilizes spatially offset-coupled apertures (SOAs) and ellipsoidal microlenses on a single planar CMOS image sensor.

    a Microfabrication steps of the SOEMLA camera. The SOAs were defined on both sides of a borosilicate glass wafer by using Cr evaporation and lift-off process (step I). Elliptic microcylinders were photolithographically defined and reflowed into ellipsoidal microlenses via resist melting (step II-III). Finally, the SOEMLAs were mounted onto a single CMOS ISA with alumina spacers (step IV). b Optical image of the microfabricated SOEMLAs with variable sizes and asymmetry. The ellipsoidal microlenses feature radially arranged curvatures with variable spatial offsets to reduce astigmatism and field curvature in wide FOV imaging. Scale bar: 1 mm. c 3D surface map of the ellipsoidal microlens highlighted by the red box in b, measured by confocal laser scanning profilometer. The black dashed line represents the size of the central spherical microlens for reference (left). Comparison of the microfabricated ellipsoidal microlens profile with its optical design (right). Cross-sectional profiles along the major (X-X′) and minor (Y-Y′) axes show strong agreement between the measured data and the optical design. Scale bar: 100 μm. d Radius of curvature (ROC) of the ellipsoidal microlenses. The ROC increases with the visual axis angle to correct the field curvature, while the difference between the ROCs of the major and minor axes diverges to reduce astigmatism. The measured ROC values align closely with the target values, indicating a high level of precision (average error: 0.88%) in microfabrication. e Captured image of the fully packaged SOEMLA camera. Scale bar: 5 mm.

    a Astigmatism correction of a single ellipsoidal microlens. Optical sectioning of ellipsoidal microlenses with different aspect ratios (ARs). All microlenses share the same focal length along the major axis but have different focal lengths along the minor axis. Captured images show sharp focus in both tangential and sagittal directions with an ellipsoidal microlens AR of 0.90, closely matching the theoretical value of 0.86. Scale bar: 100 μm. b Measured MTF50 for the visual axis angle of 20° depending on the aspect ratio of ellipsoidal microlenses. The ellipsoidal microlens (AR: 0.90) significantly reduces astigmatism caused by the visual axis deviates further from the optical axis. T and S denote the tangential and sagittal directions. c Measured MTF50s and d captured line pair images at various incidence angles for spherical microlens (blue), SOMLA (green), and SOEMLA (red) cameras. The SOEMLAs exhibit exceptionally high and balanced MTF50 values on both planes across the field. The resolution gain, i.e., the SOEMLA-to-spherical MTF50 ratio, increases sharply at large incidence angles. e Size comparison of SOEMLA camera (TTL: 0.94 mm, diagonal FOV: 140°) and a commercial compact wide-angle camera (TTL: 8.3 mm, diagonal FOV: 120°). Scale bar: 5 mm. f Measured MTF50 as a function of working distance for the SOEMLA and commercial cameras at incidence angles of 0° (top) and 45° (bottom). The commercial camera (focused at 50 mm) shows shallow DOF, while the SOEMLA camera maintains uniform resolution over a wide range without astigmatism.

    a Image processing procedure. The camera calibration allows for uniform brightness and distortion-free images while determining the warping matrix. After array image capture, distortion-corrected images are stitched via homography transformation (HT) with weighted blending. b Calculation of the reprojection error from the ArUco target’s corner ground truth (GT, green) and reprojected points (RP, red) with overlaps in blue. The RP data from each partial image determines the warping matrix for HT. c Reprojection errors across the full FOV. Reprojection errors from the central ( ± 0–30°) to the mid-frame ( ± 15–55°) and peripheral ( ± 30–70°) regions consistently remain around 1.1–1.3 pixels, demonstrating high calibration accuracy and minimal aberration for precise image stitching. In the box plot, the center line indicates the median, the box represents the 25th–75th percentiles, and the whiskers extend to 1.5 × the interquartile range. Each microlens is spirally indexed from the center of 5 × 7 arrays. d Partial images captured by the SOEMLA camera of the wasp (top) and butterfly (bottom) displayed on an LCD screen. Each partial image corresponds to a different visual axis angle, with adjacent images redundantly overlapping for seamless stitching. The reference target images are displayed on the bottom right. e Fully stitched wide FOV images. The reconstructed images exhibit minimal aberration and closely match the original screen across the wide FOV (horizontal: 120°, vertical: 90°, diagonal: 140°).

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: Here we report spatially offset ellipsoidal microlens array (SOEMLA) camera for low-aberration wide FOV imaging, inspired by the vision scheme of Xenos peckii .
