“…A similar sudden drop in cantilever Q at an air-liquid interface has been observed using a bent NSOM fiber probe in water 15 and a bent tungsten AFM probe immersed into liquid paraffin. 20 In both these experiments the probe oscillation is parallel to the vertical portion of the probe ͑i.e., tapping or intermittent contact mode͒ and laser deflection distance regulation occurs from the top surface of the horizontal part of the cantilever.…”

“…It would appear that our probe vibration is not confined to just vertical oscillation and must include some torsional motion, i.e., causing motions perpendicular to the axis of the vertical portion of the probe. Using a similar bent low spring constant fiber probe Muramatsu et al 15 observed that dragging the probe tip on a surface in contact mode could also excite such torsional modes of oscillation. One can define a torsional spring constant ͑k tor ͒ analagous to the formula to calculate the cantilever spring constant ͓Eq.…”

“…These limitations can be addressed by implementation of a low stiffness probe design such as described in Ref. 15. In this paper we provide a detailed characterization of the damping behavior in water of high and low spring constant bent fiber probes.…”

“…Furthermore, damping can also cause a decrease in the cantilever resonance frequency compared to that in air. 16,17 Although some aspects of bent fiber NSOM probe damping have been described previously, 15,[18][19][20] there is a clear need for a thorough study of the damping behavior. The experimental results provided here show the dramatic damping of bent fiber probes as they enter an air-water interface.…”

The damping behavior of bent fiber near-field scanning optical microscopy ͑NSOM͒ probes operating in tapping mode oscillation is investigated in air and water. We show that the significant drop in probe quality factor Q, which occurs at the air-water interface, is due to meniscus damping. As the probe is immersed in water viscous damping adds to the meniscus damping. Damping effects which lead to a progressive drop in the peak tapping mode resonance frequency are accounted for by additional torsional modes of probe vibration. Understanding the damping processes should lead to the design of high sensitivity NSOM probes for scanning soft biological samples under liquid.

SummaryWe have developed a high-speed scanning near-®eld optical microscope (SNOM)/atomic force microscope (AFM) system including dual feedback controllers. The system includes an additional piezoelectric actuator with fast response in the z direction and a correction circuit to eliminate unnecessary components from the feedback signal. From the measurement of a patterned chromium layer of 2´2 mm 2 checks on a quartz glass plate, we con®rmed that our system had more effective feedback control and faster scanning than current SNOM/AFM systems that use only a piezo-tube. The scanning speed of the present system was estimated to be about ®ve times faster than that of current SNOM/AFM systems.
