The trapping force is generated by the interaction between the laser light and the particle, which can be precisely controlled by adjusting the laser intensity and polarization. In addition, fiber optic tweezers can also be used as a vibration sensor due to the high sensitivity of the fiber optic sensing element to external forces. Objectives: The objectives of this research are to investigate the capture and vibration sensing characteristics of fiber optic tweezers, and to develop a comprehensive understanding of their working principles and performance. Specifically, the research will focus on the following aspects: 1. The effect of laser intensity and polarization on the trapping force and capture efficiency of fiber optic tweezers.2. The optimization of fiber optic tweezers design parameters, such as focal length, NA (numerical aperture), and fiber diameter.3. The development of a vibration sensing system based on fiber optic tweezers, and the investigation of its sensitivity, frequency response, and signal processing algorithms.Methodology: The research will utilize a combination of experimental and theoretical approaches to investigate the capture and vibration sensing characteristics of fiber optic tweezers. The experimental work will involve the construction of a fiber optic tweezers system and the measurement of its trapping force, capture efficiency, and vibration sensing performance. The theoretical work will involve the development of numerical simulations and analytical models to predict the behavior of the system under different conditions.Expected outcomes: 精品文档---下载后可任意编辑The expected outcomes of this research include a comprehensive understanding of the capture and vibration sensing characteristics of fiber optic tweezers, and the development of optimization strategies and signal processing algorithms to improve their performance.
