Abstract (en)

[origin: WO2014123536A1] In various embodiments, an optical fiber module (100) includes an optical fiber (101) having a first end (102), a second end (104), and a twisted portion (106) between the first (102) and second ends (104) to enable the optical fiber (101) to provide two orthogonal transverse bending degrees of freedom. The twisted portion induces an optical distortion. The module (100) further includes a distortion compensation arrangement (108) that is configured to at least partially compensate for the optical distortion and a housing (110) that is configured to house at least a portion of the optical fiber (101) including the twisted portion.
