研究目的
Investigating methods to lower the resonance frequency of a single fiber scanner for applications in minimally invasive surgery and OCT.
研究成果
The study demonstrated that placing a weight on the fiber cantilever end effectively lowers the resonance frequency. The experimental results agreed well with theoretical simulations, providing a foundation for further research on scanner technologies.
研究不足
The fiber cantilever is very susceptible to environmental changes, making the scanner characteristic more complex due to its nonlinearity.
1：Experimental Design and Method Selection:
The study proposed a new method to lower the resonance frequency by placing a weight on the fiber cantilever end. Theoretical simulations and experimental measurements were conducted to validate the method.
2：Sample Selection and Data Sources:
A single fiber scanner assembly was used, consisting of optical fiber, piezoelectric actuator tube (PZT-5A), insulation collar, holder, steel tube as the weight, lens assembly, and joint between the piezo-tube.
3：List of Experimental Equipment and Materials:
Piezoelectric ceramic tube (PZT-5A), steel tube (OD of
4：5mm and ID of 2mm), optical fiber, epoxy, instant glue. Experimental Procedures and Operational Workflow:
The fiber and piezo-tube were combined using epoxy, and other objects were attached with instant glue. The driving voltage controlled the scanning amplitude of the fiber end.
5：Data Analysis Methods:
The resonance frequency was measured and compared with simulation results.
