The unique structures of biological vision systems in nature inspired scientists to design ultracompact imaging systems. Researchers have made an ultracompact camera that captures high-contrast and high-resolution images. Fully packaged with micro-optical elements such as inverted micro-lenses, multilayered pinhole arrays, and gap spacers on the image sensor, the camera boasts a field of view of 73°.
