More Information
Summary:Various techniques are disclosed to provide for reducing undesired reflections in captured images. In one example, a system includes an optical element configured to pass radiation from a scene. The system also includes an imager configured to capture images in response to the scene radiation and reflect at least a portion of the scene radiation to the optical element. The optical element comprises a surface with a convex radius of curvature facing the imager and configured to receive and return the reflected radiation toward the imager in a distribution pattern to reduce a magnitude of the reflected radiation in the captured images. Additional methods, devices, and systems are also provided.
