A voltage change across the switchable mirror element generates a change in the reflection and transmission properties of the element, such that the element switches between a mirror state and a lens state. When nested in an annular reflective optic system of a given field of view, the switching element enables the opening of an additional optical path through the center of the reflective optics where a set of refractive optics are assembled into an imaging system for a second field of view. This dual field-of-view system changes field of view with no mechanical movement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual field of view annular folded optics with switchable mirrored surface","description":"An optical system that images a scene at two different fields of view, with switching between fields of view enabled by switchable mirrored surface is disclosed.
