Abstract

We present a novel method to calibrate fiber optical tweezers. This paper proposed a new calibrating method solving the problem, which makes the calibration for fiber optical tweezers in a wide range of output optical field possibly. Based on electromagnetic field momentum conservation law and finite-difference time-domain method, we calculated and analyzed the force of multiple particles are simultaneously trapped, and get the f-x (trapping fore-distance from the fiber tip) curve, which is consistent to the experimental results. Theoretical and experimental results show that the fiber optical tweezers is more conducive to study the precise mechanical properties of biological cells in a larger range.
