Title: Klaus Dransfeld: Innovator in Acoustic Scanning Technology
Introduction
Klaus Dransfeld is a notable inventor based in Ermatingen, Switzerland. He has made significant contributions to the field of acoustic scanning technology, holding a total of 3 patents. His innovative work has paved the way for advancements in microscopy and data retrieval methods.
Latest Patents
One of Dransfeld's latest patents is an acoustic screen scan microscope designed for the examination of objects. This microscope utilizes the damping of a resonant acoustic oscillator and an acoustic near-field effect. In a preferred embodiment, a 32 KHz tuning fork serves as an acoustic oscillator, achieving a vertical resolution of 5 nm and a horizontal resolution of 50 nm at a minimum distance of approximately 50 nm. The frequency or amplitude variation of the resonant acoustic oscillator can be employed, with the acoustic near-field effect being dependent on the coupling medium, such as air, and the pressure conditions.
Another significant patent involves a process for reading out information from electrically polarizable data. This method scans and selects information recorded in a data carrier through locally variable electric polarization using an electron beam. Secondary electrons produced on the surface of the data carrier are utilized, while the data carrier is periodically heated or charged with ultrasonics. This process results in potential fluctuations that modulate the secondary electron flow, allowing for the recovery of stored information.
