Abstract: According to examples, an optical fiber-based sensing membrane may include at least one optical fiber, and a substrate. The at least one optical fiber may be integrated in the substrate. The substrate may include a thickness and a material property that are specified to ascertain, via the at least one optical fiber and for a device that is contiguously engaged with a surface of the substrate, includes the substrate embedded in the device, or includes the surface of the substrate at a predetermined distance from the device, a thermal and/or a mechanical property associated with the device, or a radiation level associated with a device environment.

Abstract: An apparatus for providing an improved coupling link with integrated beam blocking and a bearing assembly using an axial preloading technique is disclosed. The apparatus may include a coupling link comprising a first end, a second end, and a middle section. The middle section may be connectable to a beam blocking element. The first end may include a first bearing assembly and may be connectable to a motor drive arm. The second end may include a second bearing assembly and may be connectable to an optical-mechanical element. In some examples, the apparatus may be used in various optical measurement and testing applications and environments. In some examples, the improved coupling link may also utilize an axial preloading technique to minimize excessive movement in bearings assemblies.
