    • The analyzer is equipped with a source of polychromatic light (ZSP), optical spectrometer with multi-segment photo detector (FD), and acousto-optic transducer (PAO) placed in the route of light beam, fitted with an piezoelectric transducer (PP) connected with a source of RF signals that generates acoustic wave creating a Bragg grating in the area of wave propagation. The acousto-optic transducer (PAO) includes a short optical fiber section (D), to the base of which piezoelectric transducer (PP) is attached, while the opposite end of the short section (D) is connected with the second optical fiber section (B) connected via beam splitter (DW) with the first optical fiber section (A), to which the source of polychromatic light is attached, and the third optical fiber section (C), to which the optical spectrometer is connected, while the piezoelectric transducer (PP) is situated at the extension of optical axis of the second optical fiber section (B). Another acousto-optic transducer (PAO) includes a gradient lens composed of two coaxially connected parts (Gl, G2), while the piezoelectric transducer (PP) is attached to the base of the first part (Gl), and the base of the second part (G2) is connected with the second optical fiber section (B).

    • A method of attaching measurement data to an area map on the display of a test instrument includes importing a map for display covering a desired spatial region. Appropriate points of interest are overlaid on the map. A user selects measurement data to be attached to the map and, upon selection such as by "tapping" a touch sensitive screen, a measurement icon is positioned on the map where the selected measurement data was acquired. A thumbnail of the selected measurement data is overlaid on the measurement icon to show both the type of measurement and actual measurement results. Also indicia of quality/strength for the measured signal may be tagged to the measurement icon, such as by changing the color of the border of the measurement icon accordingly. A direction arrow may also be associated with the measurement icon to indicate an orientation of the test instrument when the measurement data was selected.
    • 将测量数据附加到测试仪器的显示器上的区域图的方法包括导入覆盖所需空间区域的显示图。 适当的兴趣点覆盖在地图上。 用户选择要附加到地图的测量数据,并且在诸如通过“敲击”触敏屏幕的选择之后,测量图标位于获取所选择的测量数据的地图上。 所选测量数据的缩略图覆盖在测量图标上,以显示测量类型和实际测量结果。 也可以将测量信号的质量/强度的标记标记为测量图标,例如通过相应地改变测量图标的边界的颜色。 当选择测量数据时,方向箭头也可以与测量图标相关联以指示测试仪器的方位。
