    摘要: Aspects are generally directed to a compact anamorphic objective lens assembly. In one example, the objective lens assembly includes a first anamorphic lens group including a first cylindrical lens having a surface optically powered in a first dimension and a second cylindrical lens having a surface optically powered in a second dimension orthogonal to the first dimension, the first anamorphic lens group being positioned to receive visible light along an optical path, a second anamorphic lens group positioned along the optical path to receive the visible light from the first anamorphic lens group, the second anamorphic lens group including a third cylindrical lens having a surface optically powered in the first dimension and a fourth cylindrical lens having a surface optically powered in the second dimension, and an aperture stop centered along the optical path and interposed between the first and second anamorphic lens groups.

    摘要: 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.

    摘要: 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.
