Description:: In this research project, particle sorting of Brownian liquids was explored by sweeping two noncoherent pairs of parallel optical standing waves in a translating medium. Each wave was created by interfering two coherent beams of light, and the resulting fringe periods were determined by the angle of intersection. Adjusting the...

Description:: In this study, particle sorting and transportation in Brownian liquids were explored by translating an optical standing wave. The standing wave is produced by crossing two coherent beams of light, and determining the resulting period by the angle of the intersection. Adjusting the period and velocity of wave ridges allows...

Description:: This project involved the study of Brownian motion of polystyrene microspheres in the presence of gravity and a one-dimensional sinusoidal optical potential generated by the interference of two laser beams. An exponential relationship was observed between applied laser power and particle residence time of individual interference fringes. Increasing laser power...
