Design and calibration of optical tweezers using the power spectrum method
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
The aim of this experiment was to calibrate the optical tweezers by using the power spectrum method. We constructed an optical tweezers which was steerable in the x and y directions. The experimental setup contained three parts mainly: particle trapping, illumination and data processing. The system could manipulate and observe the particle. Our results showed that the trap stiffnesses are both 0.507pN/μm in x and y axis for 1 μm bead.
