True Tapping Mode Scanning Near-Field Optical Microscopy with Bent Glass Fiber Probes

Figure 3

Rotation of the tip (initial ) results in the change of the factor. (a) It can be seen the geometry of problem: bent fiber attached to the TF in double resonance condition is tilted relative to the sample. Rotation angle is shown in (b). One can see that the rotation in the negative direction is limited by the very sample.
