    • A damage sensor for detecting damage within a structure such as aircraft wings or fuselage, or a bridge. The sensor comprises a small piece of a triboluminescent material connected via light guiding fibres or layers to one or more detectors. The sensor may be embedded within the structure or mounted on its surface. Impact of objects on the structure causes a physical damage to the triboluminescent material. Such damage causes light emission which is detected and recorded for later observation. The intensity of emission may be measured to give an indication of amount of damage received by the structure. Several different triboluminescent materials may be arranged in different locations within the structure so that location of damage may be detected by a single detector sensitive to the different wavelengths of light emitted by the several materials. Light from the triboluminescent material may be detected directly by the detectors. Alternatively, material doped with suitable photo excitable dyes may be caused to photo excite, and the resultant light output detected.
    • 用于检测诸如飞机机翼或机身或桥梁之类的结构中的损坏的损伤传感器。 传感器包括通过导光纤维或层连接到一个或多个检测器的三块发光材料的小块。 传感器可以嵌入结构内或安装在其表面上。 物体对结构的影响会导致对三元发光材料的物理损伤。 这种损坏会导致发光并被记录以便稍后观察。 可以测量发射强度以给出由结构接收的损伤量的指示。 可以在结构内的不同位置布置几种不同的三色发光材料,从而可以通过对由多种材料发射的不同波长的光敏感的单个检测器来检测损伤位置。 可以通过检测器直接检测来自三溴发光材料的光。 或者,可以使掺杂有合适的光可激发染料的材料进行光激发,并检测所得光输出。
