Abstract :
Summary form only given. Quartz tuning forks, driven to electromechanical resonance by piezo elements, are widely used as distance sensing elements in scanning near-field optical microscopy (SNOM). Distance controls, based on tuning forks without piezo elements, have been successfully employed in atomic force microscopes. We extended this technique to the case of low temperature SNOM. In our experimental set-up, the fibre is fixed at two points.
