Embodiment Construction
[0038] Target moment measuring device of the present invention, see Figure 4 , including an optical fiber sensor (1), a light source (5), a photodetector (6), a photodetector signal processing module, a timing module, and an information collection and processing module.
[0039] see figure 2 The optical fiber sensor (1) is a single sensing optical fiber, which is reciprocally arranged in the target, covering the area of the target target surface, and the arrangement distance is smaller than the diameter of the area (2) formed by the target in the test bomb; the light source (5) The emitted optical signal is incident into the optical fiber sensor (1) through the first optical fiber connector (3), and then transmitted to the photodetector (6) through the second optical fiber connector (4). The light source adopts a laser light source or a light-emitting diode, and the optical fiber connector adopts a single-core connector with an insertion loss less than 0.4dB. The optical ...
