Optical Particle Sorting in Translating Brownian Liquids

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...

Diffusion of Spherical Polystyrene Particles through a Tilted Washboard Potential

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...
