  • Patent number: 11221448
    Abstract: An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

  • Publication number: 20210347194
    Abstract: A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

  • Publication number: 20200039279
    Abstract: An optical product can reproduce a first 3D image of at least part of a first 3D object and a second 3D image of at least part of a second 3D object. The optical product comprises a surface configured, when illuminated, to reproduce by reflected or transmitted light, the first 3D image without reproducing the second 3D image at a first angle of view, and the second 3D image without reproducing the first 3D image at a second angle of view. Each portion of first portions can correspond to a point on a surface of the first 3D object, and comprise first non-holographic features configured to produce at least part of the first 3D image. Each portion of second portions can correspond to a point on a surface of the second 3D object, and comprise second non-holographic features configured to produce at least part of the second 3D image.

  • Patent number: 9877649
    Abstract: Systems and methods are provided for performing a photorefractive assessment. The system comprises a computing device including an image-capturing device, a display device, and a computer application that is executable on the computing device and operable to perform a method including receiving input specifying subject information, capturing an image using the image-capturing device containing eye pupils of a subject, and analyzing the image captured to determine a distance between the subject and the image-capturing device using the subject information and predetermined interpupilary distance information. A remediation action may be performed if the distance determined is not within an appropriate distance range for the photorefractive assessment. An illuminance level of the environment may be analyzed using the image captured to determine whether lighting conditions are appropriate for performing the photorefractive assessment.

  • Publication number: 20170112373
    Abstract: Systems and methods are provided for managing, optimizing subject information, recommending ophthalmologic assessments, and performing diagnostic assessments. The system includes a computing device having an image-capturing device and a display. The system includes a computer application that is executable on the computing device and operable to receive information regarding a subject, recommend ophthalmologic tests based on the information received, and perform ophthalmologic assessments on a subject. Performance of the ophthalmologic assessments causes the application to generate information regarding the ophthalmologic health of the subject, analyze the information generated, and present results of the analysis on the display.

  • Patent number: 8570356
    Abstract: An imaging system. An array of light sources and an array of lenses corresponding to the light sources and having optical axes substantially parallel to one another are provided. The lenses produce collimated output beams. An afocal optical relay having an optical axis substantially parallel to the optical axes of the lenses is also included, the array of lenses being positioned relative to the afocal optical relay so as to form an optical system that produces an image of each collimated output beam on an image plane, each image having a prescribed depth of focus and spot size. The light sources preferably are lasers producing an array of respective laser beams having high intensity and a long waist. A system for writing information on a light-sensitive label includes the imaging system. Methods of imaging and of writing information on a light-sensitive label are also provided.

  • Publication number: 20100328471
    Abstract: A multi-channel camera system for capture of still or video images includes multiple fixed focal length lenses and multiple digital sensors in a compact package. A preferred embodiment of the invention is wearable, and is intended to be head-mounted near a user's eye to capture, in real time, the user's perspective view of a scene. The multi-channel lens system sub-assembly preferably includes three fixed focal length lenses—a wide angle lens, a standard lens, and a telephoto lens,—each providing a different field of view. Lens elements are arranged in a monolithic integrated structure, and optionally separated from each other by light-absorbing baffles to minimize cross-talk between the channels. The camera system includes circuitry to select one or more lenses, capture and compress a series of images, and transfer the images for storage on a remote device. Standard communication protocols may be used for wireless image data transfer.
