    • Remote platform enhanced munitions detection can support improved detection of munitions by separating the signal source platform from a detector on a remote mobile platform. The source platform may support a large, complex, or expensive optical laser or radio frequency source. The source platform may also support a remote signal processing system. The electromagnetic source may be used to illuminate munitions or threat material from a standoff distance. The mobile platform may be maneuvered and positioned closer to the measurement target. The mobile platform may be equipped with an appropriate electromagnetic detector to obtain measurement data at different ranges and positions around the measurement target. The mobile platform may also provide an articulating arm with a mirror or reflector to support non-line-of-sight measurements.
    • 远程平台增强的弹药检测可以通过将信号源平台与远程移动平台上的检测器分开来支持改进弹药的检测。 源平台可以支持大型,复杂或昂贵的光学激光器或射频源。 源平台还可以支持远程信号处理系统。 电磁源可用于从隔离距离照射弹药或威胁材料。 移动平台可以被操纵并定位成更靠近测量目标。 移动平台可以配备有适当的电磁检测器,以在测量目标周围的不同范围和位置处获得测量数据。 移动平台还可以提供具有反射镜或反射器的铰接臂以支持非视距测量。

    • Methods are provided for testing a honeycomb body comprised of a core portion comprising honeycomb cell walls and a circumferential skin portion overlying at least some outer honeycomb cell walls. The circumferential skin portion includes a cement mixture layer. The method comprises the step of directing a fluid stream from a pressurized fluid source at the honeycomb body. The fluid stream is capable of separating at least part of the skin portion from the outer honeycomb cell walls when the adherence between at least part of the skin portion and the outer honeycomb cell walls is below a minimum threshold. In one example, the method further comprises the step of inspecting at least part of the interface between the honeycomb body and the skin portion during or after directing the fluid stream at the honeycomb body.

    • A target gas sensing system includes a single source at a first location for generating two light beams having first and second frequencies wherein the difference between the first and second frequencies is the Raman frequency of the target gas. A difference frequency generator outputs the two light beams having the first frequency, the second frequency, and a third light beam having a third frequency that is the difference between the first and second frequencies. The first, second, and third light beams are directed toward the target gas. An input optic directs light from the third light beam, after interacting with the target gas, to a receiver for absorption spectroscopy processing, directs a fourth light beam from the target gas to a receiver for coherent anti-Stokes Raman processing, wherein the fourth light beam has a frequency of twice the first frequency minus the second frequency.
