光学力传感器
摘要：
一种力传感器(10)，包括两个结构构件(11、12)及多个光纤(13)，两个结构构件是间隔开的，从而限定两个结构构件之间的间隙(101)，并且两个结构构件连接至彼此，多个光纤固定至结构构件，且多个光纤自由地悬置在间隙中。光纤构造成响应于两个构件之间的在一个或多个预定自由度中的相对位置中的变化而提供能检测的光学特性中的变化。所述多个光纤(13)中的每个均固定至两个结构构件并且在所述构件之间是连续的，以使两个结构构件连接至彼此。多个光纤基本上是在两个结构构件(11、12)之间形成连接的仅有的结构，使得多个光纤的布置基本上限定两个结构构件之间的连接在一个或多个预定自由度中的硬度，该硬度主要地，诸如至少95％，由多个光纤确定。
摘要（英）：

Force transducer (10) comprising two structural members (11, 12) being spaced apart thus defining a gap (101) in between and being linked to each other, and a plurality of optical fibres (13) being fixed to the members and being freely suspended in the gap. The optical fibres are configured to provide a change in a detectable optical property responsive to a change in relative position between the two members in one or more predetermined degrees of freedom. Each of said plurality of optical fibres (13) is fixed to both structural members and continuous between the members so as to link the two structural members to each other. The plurality of optical fibres are substantially the only structure forming a link between the two structural members (11, 12), such that the arrangement of the plurality of optical fibres define substantially the stiffness of the link between the two structural members in the one or more predetermined degrees of freedom, which stiffness is mainly, such as for at least 95%, determined by the plurality of optical fibres.
