    • A non-visible particle detection device includes an optical module capable of converting an ionizing radiation into visible light. The optical module includes has an attachment unit that is configured to removably attach the optical module to the image capturing module of a mobile device. The image capturing module generates a photon digital image based on the photons converted from the ionizing radiation. The mobile device can be implemented with a radiation dose determining module to execute a radiation dose equivalent calculation method. Based on the pixel brightness analysis of the photon digital image, the radiation equivalent dose can be determined. This method sums up the total brightness of all pixels in the images, determines whether the total brightness is smaller than the minimum effective brightness, and determines the radiation equivalent dose when the total brightness is equal to or larger than the minimum effective brightness.

    • A fused-fiber multi-window wavelength filter (MWF) is constructed with an unbalanced Michelson Interferometer, in which input light passing through the fused coupling region is decoupled and travels along two fibers of different optical path lengths. The two light signals travel to the end of the two fibers, where a highly reflective coating reflects the light back toward the coupling region, where the signals are coupled again and then decoupled after exiting the coupling region. By adjusting the optical path length difference, either by changing the length or refractive index, a signal at a desired wavelength can be obtained at the filter output. The MWF can be combined with other MWFs to form more compact sized multi-window wavelength division multiplexers (MWDMs) and dense WDMs. Passive thermal compensation techniques can be applied to one or both of the reflecting fibers to maintain the desired optical path length difference.
    • 熔融纤维多窗口波长滤波器(MWF)由不平衡的迈克尔逊干涉仪构成,其中通过熔融耦合区域的输入光被去耦并沿着不同光程长度的两条光纤传播。 两个光信号行进到两个光纤的末端,其中高度反射的涂层将光反射回耦合区域,其中信号被再次耦合,然后在离开耦合区域之后解耦。 通过调整光程长度差,通过改变长度或折射率,可以在滤波器输出处获得期望波长的信号。 MWF可以与其他MWF组合以形成更紧凑的多窗口波分复用器(MWDM)和密集WDM。 被动热补偿技术可以应用于一个或两个反射光纤,以保持所需的光程长度差。
