摘要： The present invention relates to a method of and a system for optically connecting an optical fiber sensor (12) to an optical shape sensing console (21). The optical shape sensing console (21) has a number of single optical channels (C1, C2, C3). The optical fiber sensor (12) has a number of single fiber cores (A1, A2, A3) angularly spaced with respect to one another around a longitudinal center axis of the fiber sensor (12) and a fiber sensor connection end (30) for connection to an optical coupler (32; 38) connected to the shape sensing console (21). The optical coupler (32; 38) has the optical channels (C1, C2, C3) arranged for optical connection with the fiber cores (A1, A2, A3). A number of single calibration data sets indicative of individual optical properties of the single fiber cores (A1, A2, A3) is assigned to the single optical channels (C1, C2, C3). The fiber sensor connection end (30) is connected to the optical coupler (32; 38) such that a first fiber core (A2) of the fiber cores (A1, A2, A3) is in optical communication with a first optical channel (C1) of the optical channels (C1, C2, C3). An optical response of the first fiber core (A2) is measured by optically interrogating the first fiber core (A2) while a first calibration data set of the calibration data sets is assigned to the first optical channel (C1). The first fiber core (A2) is identified among the fiber cores (A1, A2, A3) of the fiber sensor (12) on the basis of the measured optical response of the first fiber core (A2) and the calibration data sets of the fiber sensor (12). If the first fiber core (A2) is identified as not matching with the first calibration data set used hi measuring the optical response, then a second calibration data set of the calibration data sets, which matches with the identified first fiber core (A2), is reassigned to the first optical channel (C1), or the fiber sensor connection end (30) and/or the optical coupler (32; 38) are repositioned such that a second fiber core (A1) matching with the first calibration data set is in optical communication with the first optical channel (C1).

摘要： A display has an array of light emitting display pixels occupying pixel areas, and a polarizing light transmissive area between the pixel areas. This polarization can be used to improve the contrast ratio of a transparent 2D display. However, it can also be used to enable a transparent 3D display to be formed without distortion of the see-through transparent display function. For this purpose, the light emitting display pixels can emit polarized light orthogonal to the polarization provided by the light transmissive area.

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.
