    • A dispersive element is incorporated with an optical sensor as a spectrometer. The dispersive element includes a guided-mode resonance filter having a plurality of resonance regions. The resonance regions respectively have different filter characteristics, each reflecting a first light beam of a tested light source or transmitting a second light beam of the tested light source light source to the optical sensor, wherein the wavelength of the first light beam is different from that of the second light beam. In one embodiment, the dispersive element is incorporated with an optical sensor to form a miniature, high-resolution and low-cost spectrometer. The spectrometer makes use of the transmission efficiencies of the resonance regions of the guided-mode resonance filter and the light intensity distribution detected by the photosensitive regions of the optical sensor to acquire the spectral data of the tested light source.
    • 分散元件与光学传感器结合,作为光谱仪。 分散元件包括具有多个谐振区域的导模谐振滤波器。 共振区域分别具有不同的滤光器特性,每一个反射被测光源的第一光束或将被测光源光源的第二光束透射到光学传感器,其中第一光束的波长与 的第二光束。 在一个实施例中,色散元件与光学传感器结合以形成微型,高分辨率和低成本的光谱仪。 光谱仪利用了导模谐振滤波器的谐振区域的传输效率和由光学传感器的感光区域检测到的光强度分布,以获得测试光源的光谱数据。

    • A method for positioning a device includes the steps of: estimating an absolute distance between a reference point and the device at each of a current time point and a number (N) of consecutive previous time points, where N is a integer smaller than n, n is a non-negative integer indicating a total number of time points since the device starting to move, and the current time point is defined as the (n)th time point; estimating a unit vector of a movement direction of the device in each of (n−N+1)th to (n)th time periods; and estimating a coordinate of a location of the device at (n)th time point based on the absolute distance(s), the unit vector(s), and a coordinate of a location of the device at each of the number (N) of the consecutive previous time points.
    • 一种用于定位设备的方法包括以下步骤:在当前时间点和连续的前一时间点的数量(N)中的每一个上估计参考点和设备之间的绝对距离,其中N是小于n的整数, n是指示从设备开始移动以来的时间点的总数,并且当前时间点被定义为第(n)个时间点的非负整数; (n-N + 1)至(n)个时间段中的每一个中估计所述装置的移动方向的单位矢量; 以及基于绝对距离,单位向量和每个数量(N)处的设备的位置的坐标来估计在第(n)个时间点的设备的位置的坐标, 的连续以前的时间点。
