Latest Patents
Dmitri N Davydov holds a patent for a "Near-field scanning optical microscope with a high Q-factor piezoelectric sensing element." This invention describes a perpendicular-mode NSOM that utilizes a piezoelectric micro tuning fork as its height-sensing element. The invention provides a method for modifying and attaching an optical fiber to the tuning fork, allowing the assembly to retain Q-factors up to 9000. This is substantially higher than previously documented for tuning-fork-based instruments. The method involves reducing the diameter of the optical fiber's cladding to between 17-25 µm through several chemical etching steps before attachment to the tuning fork. A significant increase in the Q-factor is observed when the fiber diameter drops below approximately 25 µm. The high Q-factors achieved result in improved force sensitivity, enabling the construction of a perpendicular mode instrument without additional dithering piezoelements.
