    • A system and method that includes, in an embodiment, a prism, a camera, a light source, and a plate. The system, in an embodiment, is configured for scanning a roll and generating an image of the roll surface. The prism, in an embodiment, is positioned below the camera and above the plate. In an embodiment, the plate is positioned below the prism and above the roll surface. In an embodiment, the light source is positioned above the prism. In an embodiment, the light source and the prism are positioned to provide light to the roll surface at an angle of at least 75 degrees measured from a line normal to the roll surface. In an embodiment, the prism is configured to refract light from the light source, the camera is a line scan camera that includes a row of pixel sensors, and the light source includes light emitting diodes.
    • 在一个实施例中包括棱镜,照相机,光源和板的系统和方法。 在一个实施例中,该系统被配置用于扫描辊并产生辊表面的图像。 在一个实施例中,棱镜位于照相机下方和板的上方。 在一个实施例中,板位于棱镜下方并在辊表面上方。 在一个实施例中,光源位于棱镜上方。 在一个实施例中,光源和棱镜被定位成以与垂直于辊表面的线测量的至少75度的角度向辊表面提供光。 在一个实施例中,棱镜被配置为折射来自光源的光,照相机是包括一排像素传感器的行扫描照相机,并且光源包括发光二极管。

    • Camera arrangements that can include electromagnetic protection, such as from EMP/IEMI events, is disclosed. One example camera arrangement includes a camera including a viewfinder having a lens, and an electromagnetically shielded enclosure defining an interior volume containing the camera and configured to include at least one opening aligned with the lens. The camera arrangement includes a waveguide beyond cutoff disposed across the at least one opening, the waveguide beyond cutoff including a plurality of cells sized and oriented to shield the interior volume of the enclosure from electromagnetic signals while exposing an optical path between the lens and objects external to the enclosure.
    • 公开了可以包括诸如来自EMP / IEMI事件的电磁保护的照相机布置。 一个示例性相机布置包括包括具有透镜的取景器的照相机和限定包含照相机的内部空间的电磁屏蔽外壳,并且被配置为包括与透镜对准的至少一个开口。 照相机装置包括跨越至少一个开口的超越截止的波导,超越切除的波导包括多个单元,其大小和取向以将外壳的内部空间屏蔽电磁信号,同时暴露在透镜和对象外部之间的光路 到外壳。
