    • The invention relates to an optical strain gauge strip (D), made from a planar support layer (6) preferably of plastic and a cover layer (19) between which an optical fibre (2, 3, 4) has a frictional fit. The optical fibre (2, 3, 4) comprises at least one section (L) with a Bragg grating (5) for recording the strain on a deformable body or a different component region. The invention is characterised in that the optical fibre (2, 3, 4) is let into at least one guide channel (7, 8, 9) in the support film forming the support layer (6). Said guide channel (7,8, 9) with the optical fibre (2, 3, 4) and the Bragg grating (5) embossed therein is sealed with a covering film as outer layer (19), made from the same material as the support layer (6).
    • 本发明涉及一种光学应变计(D,其(从平面支撑层6)优选由塑料制成和覆盖层(19),至少一个光学波导(2,3,4)被布置非主动之间,上述光波导路(2,3 ,4)具有与一个布喇格光栅(5),用于检测一个变形体或其他成分范围的伸长率的至少一个部分(L)。本发明的特征在于,所述光波导(2,3,4)内的至少一个引导件提供的信道 (7,8,9)被嵌入在支承薄膜作为载体层(6),该导引通道(7.8,9)与光波导(2,3,4)和外加在其中布拉格光栅(5)设置有一个 封闭罩膜作为由相同的材料作为载体箔(6)的顶层(19)。
