OPTICAL SYSTEMS INCLUDING META-LENSES

原文（中国語）

Systems and techniques are provided for optical systems including meta-lenses. For example, an apparatus can include an image sensor including a surface having a first region and a second region, the surface intersecting with an optical axis. The second region extends beyond one or more edges of the first region. The apparatus includes a substrate including a meta-lens, the optical axis intersecting with the meta-lens and the substrate. A cross-section of the substrate extends beyond the second region of the image sensor in at least one direction along the surface of the image sensor. The apparatus includes a spacer structure disposed between the substrate and the image sensor.
