Folded optic array camera using refractive prisms
Abstract:
Aspects relate to a prism array camera having a wide field of view. For example, the prism array camera can use a central refractive prism, for example with multiple surfaces or facets, to split incoming light comprising the target image into multiple portions for capture by the sensors in the array. The prism can have a refractive index of approximately 1.5 or higher, and can be shaped and positioned to reduce chromatic aberration artifacts and increase the FOV of a sensor. In some examples a negative lens can be incorporated into or attached to a camera-facing surface of the prism to further increase the FOV.
