    • A system and method for measuring the profile of an external surface of a part is provided. The system includes a source of light that directs light onto a region of the external surface of the part. The system also includes a linear, light-sensitive sensor, and a lens used to image locations within the region onto the sensor. The source of light and the sensor are located substantially within the same plane such that the sensor detects substantially only light scattered, diffracted, or reflected from the region and travelling substantially within the plane. The system additionally includes a re-positionable mirror that re-directs the light emitted from the source of light to the plurality of locations within the region and re-directs light scattered, diffracted, or reflected from the plurality of locations within the region to the lens and the sensor. An automatic gain control system which controls the output power of the source of light to thereby avoid saturating the exposure of the sensor may also be included in the above system. Further, a spring which functions as a low-pass filter may be used to couple the motor to the shaft of the rotating mirror. In another embodiment, a re-positionable polygon mirror system comprising standoffs with tangs which restrict the outside reflecting mirror surfaces to pre-aligned planes during rotation of the polygon mirror system is disclosed. A fail-safe eye safety technique is also disclosed which controls the power to the source of light. Even further, an optical scanning system is disclosed which utilizes bi-cell photo-detectors to determine the angular position of the source of light with high precision.
    • 提供了用于测量零件外表面轮廓的系统和方法。 该系统包括将光引导到部件的外表面的区域上的光源。 该系统还包括线性,光敏传感器和用于将区域内的位置成像到传感器上的透镜。 光源和传感器基本位于相同的平面内,使得传感器基本上仅检测到从该区域散射,衍射或反射的光并且基本上在平面内行进。 该系统还包括可重新定位的反射镜,其将从光源发射的光重新引导到该区域内的多个位置,并且重新引导从该区域内的多个位置散射,衍射或反射的光, 镜头和传感器。 控制光源的输出功率以避免饱和传感器曝光的自动增益控制系统也可以包括在上述系统中。 此外,用作低通滤波器的弹簧可以用于将电动机耦合到旋转镜的轴。 在另一个实施例中,公开了一种可重新定位的多面镜系统,其包括具有柄脚的支座,其在多面镜系统的旋转期间将外部反射镜表面限制为预对准的平面。 还公开了一种控制光源的功率的故障安全眼睛安全技术。 更进一步地,公开了一种光学扫描系统,其利用双电池光电检测器以高精度确定光源的角位置。

    • A radioaerosol delivery apparatus particularly adapted for the subsequent disposal of radioactively contaminated elements is described. The apparatus includes a shielding container including an outer shell and an inner shell supported within the outer shell. The inner shell is formed with an inner wall and an outer wall defining a space therebetween for receiving radiation shielding material. The inner wall is formed to provide a surface conforming substantially to the contour of the radioaerosol source and a surface conforming substantially to the contour of a portion of a transport manifold supported thereon. A removable cover including radiating shielding material is formed with a portion conforming generally to the contour of the transport manifold. The inner wall of the container and the cover define at least one opening therebetween to permit fluid communication from the transport manifold to a patient utilizing the apparatus.
