摘要： A design method of a multi-zone grouped and light-homogenized Fresnel lens for a concentrating system includes: step 1, designing, according to a basic principle of a Fresnel lens, a planar Fresnel lens; step 2, establishing, according to an optical path characteristic of the concentrating system, an optical path equation of the concentrating system; step 3, determining a differential form of uniform distribution of luminous energy density; and step 4, based on the step 3, calculating design parameters of the multi-zone grouped and light-homogenized Fresnel lens to obtain the multi-zone grouped and light homogenized Fresnel lens. The obtained Fresnel lens can realize low-power concentrating, solve the problem that luminous energy is too concentrated under a high-power light-concentrating ratio, achieve high-uniformity design under different light-concentrating ratios, and improve the light-homogenized performance of the concentrating system, thereby solving non-uniform luminous energy density distribution on a surface of a photovoltaic cell.

摘要： Optics for a transmission and/or reception element configured to emit and/or receive a signal in a main radiation direction has an optical body formed of a material optically transparent for the communication wavelength. It has a cavity within which the transmission/reception element is arranged, wherein a first interface is formed between the cavity and the optical body. Furthermore, the optical body has a second interface formed opposite the cavity and a lateral interface having a total internal reflection region. The first interface forms a first central lens region and a first refraction region surrounding the first central lens region. The second interface forms a second central lens region and a second refraction region surrounding the second central lens region. All the surfaces or areas described are defined to be freeform areas so that they can exhibit any shape. In addition, it is conceivable to introduce Fresnel patterns in the surfaces.

摘要： Described are examples of adjustable focus glasses formed using liquid crystal. A pair of adjustable focus glasses can include a frame and two lenses arranged on the frame. In some examples, at least one of the two lenses is a lens assembly that includes a plano-concave lens, a Fresnel lens, and a liquid crystal layer between the plano-concave lens and the Fresnel lens. The plano-concave lens includes a planar surface and an opposing concave surface. The Fresnel lens includes a Fresnel surface and an opposing convex surface. The planar surface and the Fresnel surface face the liquid crystal layer. The focus position of the lens assembly can be adjusted through changing the refractive index of the liquid crystal layer, using appropriate control signals from an electronic controller. This conveniently allows the adjustable focus glasses to be multi-purpose and suitable for correcting both myopia and hyperopia.

摘要： Anti deep fake headgear distorts the path of light rays passing from a wearer's face. The distortion effect is random due to the headgear having optical distortion devices which dangle freely in front of the wearer's face and may both swing in two dimensions and rotate in a third dimension or may themselves bend. A circlet or bridge with temples and temple tips is worn about the crown of the head or around the face from ear to ear, with an extension from the front carrying one or more suspension members in turn carrying one or more optical distortion devices. The suspension members may be limber members and the optical distortion devices may be lenses, Fresnel lenses, strips of transparent or translucent and flexible materials, Fresnel lenses, material simply having a refractive index different than air, etc.

The photodetector (101) has a center axis (102) that is lying in a center plane (001) perpendicular to a photodetector plane (002). The lens has a first lens segment (131) and a second lens segment (132) separated by the centerplane (001). The first lens segment (131) comprises a first light receiving surface (133) and a first light exit surface (135), and the first light exit surface (135) is facing the photodetector (101). The second lens segment (132) comprises a second light receiving surface (134) and a second light exit surface (136), and the second light exit surface (134) is facing the photodetector (101). The first light receiving surface (133) comprises a first convex surface with non-constant curvature, the first convex surface having a first minimum radius of curvature (051) at a first surface point. The second light receiving surface (134) comprises a second convex surface with non-constant curvature, the second convex surface having a second minimum radius of curvature (052) at a second surface point. The first angle (053) enclosed by the center axis (102) and a first line (055) is greater than zero degrees, where the first line (055) is normal to the first convex surface at the first surface point and extending up to the center axis (102). And a second angle (054) enclosed by the center axis (102) and a second line (056) is greater than zero degrees, where the second line (056) is normal to the second convex surface at the second surface point and extending up to the center axis (102).
