Digital Signal Processing for Tremor Analysis in Laser Medical Instruments

The paper aims to provide an overview on tremor problematics and existing concepts, the main topic being the digital signal processing for tremor analysis in laser medical instruments. Multiple approaches are presented during the paper for signal acquisition and instrumentation, using both analog and digital sensors. Due to high availability on the market for MEMS accelerometers and gyroscopes, carefully integrated with digital components, the primary solution treated in this paper is the digital one. Different approaches on filtering are presented, both advantages and disadvantages being underlined.
