Patent number: 12360391Abstract: An optical product can be configured, when illuminated, to reproduce an image that appears to be a 3D image of at least a part of a 3D object. The optical product can include a surface comprising a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. One or more non-holographic features can be disposed within each portion configured to produce at least part of the image without relying on diffraction. An interference optical structure can be disposed on one or more features. A gradient in the features can correlate to a surface normal of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.Type: GrantFiled: October 7, 2021Date of Patent: July 15, 2025Assignee: WAVEFRONT TECHNOLOGY, INC.Inventors: Christopher Chapman Rich, Roger Winston Phillips, Joel Mikael Petersen

For example, the optical product can be configured to be an anti-counterfeit feature such as a patch, a window, or a thread on a banknote. The optical product can be configured, when illuminated, to reproduce by reflected or refracted light, a 3D image of at least a part of a 3D object. The master can include a first surface and a second surface opposite the first surface. The second surface can include a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. Each portion can include features corresponding to non-holographic elements on the optical product. A gradient in the features can correlate to an inclination of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.Type: ApplicationFiled: July 29, 2024Publication date: June 26, 2025Inventors: Christopher Chapman Rich, Phillip Christopher Harvey, Joel Mikael Petersen

Patent number: 11624495Abstract: In one or more embodiments, a luminaire includes a housing, a light source coupled with the housing, an optical sheet coupled with the housing, and a film stabilizer coupled with the housing. The optical sheet includes a first surface and an opposing second surface that are both disposed substantially horizontally when the luminaire is in an installed orientation. The first surface is disposed facing the light source, so that when the light source emits light, the light passes first through the first surface and subsequently through the second surface. The film stabilizer includes a third surface and an opposing fourth surface. The film stabilizer is disposed with the third surface adjacent to the second surface of the optical sheet, and provides mechanical support for the optical sheet.Type: GrantFiled: August 5, 2020Date of Patent: April 11, 2023Assignee: ABL IP HOLDING LLCInventors: Jonathan Lemoine DeBow, Melissa N.
