摘要： An actuator comprises an electroactive material disposed in a gap between electrodes. The electroactive material is capable of deforming in response to an electrical stimulus such that the gap narrows towards a minimum electrode spacing. The electroactive material comprises an electroactive polymer having a first Young's modulus, and particles dispersed in the electroactive polymer. The particles have a second Young's modulus which is higher than the first Young's modulus, and occupy a volume fraction in a range of 13-35% of the electroactive material. The particles determine the minimum electrode spacing.

摘要： An optical frequency domain reflectometry (OFDR) system is provided with an optical radiation source (LS) connected to a plurality of measurement paths (MP1, MP2, MP3) and a reference path (RFP) via a first coupling point (CP1). The measurement paths (MP1, MP2, MP3) are arranged for optical connection to respective optical sensing fibers (SF1, SF2, SF3). The measurement paths (MP1, MP2, MP3) have different optical path lengths (L1, L2, L3), so as to allow an optical detection unit (ODU) to essentially uncorruptedly detect optical radiation from parts of the respectiveoptical sensing fibers (SF1, SF2, SF3) that are intended to have a sensory function. The optical detection unit (ODU) is connected to the reference path (RFP) and the measurement paths (MP1, MP2, MP3) via a second coupling point (CP2). Thus, via the common reference path (RFP) for several measurement paths (MP1, MP2, MP3), only one detection chain is required to serve several sensing fibers (SF1, SF2, SF3).

摘要： A clamp mechanism for fixation of an optical fiber (OSF) with optical shape sensing properties arranged for Optical Shape Sensing. A fixing element preferably with a circular cross section serves to engage with the optical fiber (OSF), and together with an additional fixing arrangement with a straight longitudinal portion arranged for engaging with the associated optical fiber (OSF), a fixation of a section of the optical fiber (OSF) is provided with the optical fiber (OSF) in a straight position. In some embodiments, the clamp mechanism can be implemented by three straight rods (R1, R2, R3) with circular cross section, e.g. with the same diameter being a factor of such as 6.46 times a diameter of the optical fiber (OSF). Hereby an effective fixation and straightening of the optical fiber (OSF) without disturbing strain can be obtained with a clamp mechanism which is easy to assemble and disassemble in practical applications e.g. when used as a launch fixture, and with the optical fiber (OSF) incorporated in a medical device.

摘要： There is presented an optical frequency domain reflectometry (OFDR) system (100) comprising a first coupling point (15) arranged for splitting radiation into two parts, so that radiation may be emitted into a reference path (16) and a measurement path (17). The system further comprises an optical detection unit (30) capable of obtaining a signal from the combined optical radiation from the reference path and the measurement path via a second coupling point (25). The measurement path (17) comprises a polarization dependent optical path length shifter (PDOPS, PDFS, 10), which may create a first polarization (PI) and a second polarization (P2) for the radiation in the measurement path, where the optical path length is different for the first and second polarizations in the measurement path. This may be advantageous for obtaining an improved optical frequency domain reflectometry (OFDR) system where e.g. the two measurements for input polarizations may be performed in the same scan of a radiation source.

摘要： An optical shape sensing (OSS) system with an optical console system (P, C) arranged for optical interrogation of the optical fiber cores (CC, C1, C2, C3) in the associated optical shape sensor (OSF). The optical console system (P, C) is arranged to perform optical calibration measurements on the fiber cores (CC, C1, C2, C3) with one common optical scan wavelength range (∆λ C). For each of the optical fiber cores (CC, C1, C2, C3), a measure of its optical length in calculated based on the results of the calibration measurements, preferably as ratios between outer core optical lengths and center core optical length. Individual optical scan wavelength ranges (∆λ1, ∆λ2, ∆λ3) for each of the outer cores (C1, C2, C3) are then determined according to their individual optical lengths relative to the optical length of the center core (CC), so as to compensate for optical length differences between the plurality of optical fiber cores (CC, C1, C2, C3). With this way of calibrating the OSS system, OSS interrogation can be carried out with the determined individual optical scan wavelength ranges (∆λ1, ∆λ2, ∆λ3) for each of the outer cores (C1, C2, C3), and a high OSS accuracy can be obtained since both physical length differences and refractive index differences have been aligned.
