Patent number: 11852805Abstract: A wave scanning optic is formed to have an angular reflectance or refraction that produces a uniform line scan during rotation of the optic, such that the optic is operable for seamless multidirectional scanning. The wave scanning optic includes a rotatable body defining a central axis of rotation about which the rotatable body rotates during scanning, and an optical surface formed on the rotatable body and having a wavy pattern defined by one or more lobes that protrude outwardly from the rotatable body. The optical surface has a continuous pattern with an angular frequency that varies along a radial distance from the central axis of rotation. The optical surface is configured to emit and/or receive light in one or more incident directions.Type: GrantFiled: January 5, 2021Date of Patent: December 26, 2023Assignee: Raytheon CompanyInventors: Curtis Kyhl, Mark Noethen

Patent number: 11604333Abstract: An objective lens assembly includes a first lens group configured to have a positive refractive power, the first lens group being positioned to receive visible light along an optical path extending therethrough. The objective lens assembly further includes a second lens group configured to have a negative refractive power, the second lens group being positioned along the optical path to receive the visible light from the first lens group. The objective lens assembly further includes a center lens disposed between the first lens group and the second lens group and an aperture stop centered along the optical path and positioned in front of the first lens group to direct visible light from a scene to the first lens group.Type: GrantFiled: August 25, 2020Date of Patent: March 14, 2023Assignee: RAYTHEON COMPANYInventor: Mark Noethen
