    摘要： In some examples, QR code based test data embedding and transmission may include obtaining, by a test data analyzer that is executed by at least one hardware processor, test data based on operation of a test device to measure a parameter associated with an optical fiber. Based on an analysis of the test data, a report that includes the test data may be generated. A quick response (QR) code generator that is executed by the at least one hardware processor may compress the report that includes the test data to generate a compressed report. The QR code generator may generate, based on an analysis of the compressed report, a QR code that includes the compressed report. A display generator that is executed by the at least one hardware processor may generate a display of the QR code that includes the compressed report.

    摘要： An image capture device may include a first spectral filter and a second spectral filter arranged so that a panoramic image capture operation captures light filtered by the first spectral filter and light filtered by the second spectral filter in a same region of a combined image and one or more processors to: capture a plurality of images based on the panoramic image capture operation; extract first information and second information from the plurality of images, wherein the first information is associated with the first spectral filter and the second information is associated with the second spectral filter; identify an association between the first information and the second information based on a feature captured in the plurality of images via the first spectral filter and the second spectral filter; and store or provide information based on the association between the first information and the second information.

    摘要： A multi-panel base station test system includes a base station radio unit configured with a plurality of antenna panels positioned at a first end of a test chamber of the multi-panel base station test system. The multi-panel base station test system includes a plurality of test antennas positioned at a second end of the test chamber opposing the first end. The multi-panel base station test system includes a microwave lens positioned between the plurality of antenna panels and the plurality of test antennas in the test chamber. The microwave lens is configured to focus respective beams transmitted from each of the plurality of antenna panels toward respective focal points associated with each of the plurality of test antennas based on steering of the plurality of antenna panels.

    摘要： In some implementations, an optical filter includes a first set of layers configured to pass light associated with a first wavelength range; a second set of layers configured to reflect light associated with at least one subrange of the first wavelength range; and a third set of layers configured to reflect light associated with a second wavelength range. In some implementations, the first wavelength range comprises an upper wavelength cutoff associated with a wavelength threshold, and the second wavelength range comprises a lower wavelength cutoff associated with the wavelength threshold. In some implementations, the optical filter includes a fourth set of layers configured to absorb a particular percentage of light in the first wavelength range.

    摘要： A dichroic prism beamsplitter may include a medium with a refractive index greater than approximately 1.0. The dichroic prism beamsplitter may include a plurality of layers sandwiched by the medium. The plurality of layers may include an equivalent structure including at least one layer with a refractive index that is less than a threshold refractive index for total internal reflection. The at least one layer may be associated with a thickness less than or equal to a threshold thickness associated with total internal reflection for a threshold wavelength. The at least one layer may cause total internal reflection for a first wavelength range that is less than or equal to the threshold wavelength and causes evanescent wave coupling for a second wavelength range that is greater than the threshold wavelength.
