Abstract: An optical element including an array of microlenses, a pinhole mask, and a wavelength selective filter is described. The pinhole mask includes an array of pinholes with each pinhole in the array of pinholes aligned with a microlens in the first array of microlenses. The wavelength selective filter is adapted to transmit a first light ray having a first wavelength and transmitted from a first microlens in the array of microlenses through a first pinhole in the array of pinholes aligned with the first microlens, and to attenuate a second light ray having the first wavelength and transmitted from the first microlens through a second pinhole in the array of pinholes aligned with a second microlens in the first array of microlenses adjacent to the first microlens.

Abstract: In some examples, a retroreflective article may include a retroreflective substrate, and an optical pattern embodied on the retroreflective substrate. The optical pattern may include a first optical sub-pattern and a second optical sub-pattern, wherein the optical pattern represents a set of information that is interpretable based on a combination of the first optical sub-pattern that is visible in a first light spectrum and the second optical sub-pattern that is visible in a second light spectrum. The first and second light spectra may be different.

Abstract: Gradient permittivity films are described. In particular, gradient permittivity films including a plurality of layers each having a thickness where at least one layer is perforated and has a different air volume fraction from another of the plurality of layers by at least 0.05. Such films may be useful in improving the signal to noise ratio for transmitting and receiving units operating between 20 GHz and 300 GHz behind a protective cover.

Abstract: The present disclosure includes in one instance an optical article comprising a data rich plurality of retroreflective meats that are configured in a spatially defined arrangement, where the plurality of retroreflective elements comprise retroreflective elements having at least two different retroreflective properties, and where data rich means information that is readily machine interpretable. The present disclosure also includes a system comprising the previously mentioned optical article, an optical system, and an inference engine for interpreting and classifying the plurality of retroreflective elements wherein the optical system feeds data to the inference engine.

Abstract: Optical systems are described that include a lighting component, a switchable diffuser adjacent the lighting component, and a low-absorbing optical component disposed adjacent the switchable diffuser opposite the lighting component or disposed adjacent the lighting component opposite the switchable diffuser or disposed adjacent the lighting component opposite the display panel. The switchable diffuser is capable of being in either a substantially clear state or in a first hazy state. The low-absorbing optical component provides a collimating effect or a turning effect when the lighting component is illuminated and the switchable diffuser is in the substantially clear state.

Abstract: An optical system including a lighting component and a switchable diffuser in optical communication with the lighting component. The optical system may further include a low absorbing optical component. At least one outer surface of the switchable diffuser and/or the low absorbing optical component includes light redirecting structures. When the switchable diffuser is in a first state and the optical system produces a light output, the light redirecting structures are configured to increase the full width at half-maximum (FWHM) of the light output of the optical system in at least one direction by at least 5 degrees relative to that of an otherwise equivalent optical system that does not include the light redirecting structures.
