摘要： The present invention provides system and method for three-dimensionally tracking micro particle motion wherein a dark-field condenser is configured to receive light field emitted from a light source and project the light field on a fluid sample having at least one particle thereby generating a scattered light field associated with the at least one particle, an objective lens is configured to receive the scattered light field, an image capturing unit coupled to the objective lens receives the scattered light field thereby generating at least one image of the fluid sample, and a controller is configured to couple to the image capturing unit for analyzing interference ring pattern corresponding to a specific particle in the at least one image and determining a tracking information associated with the specific particle along three-dimensional direction according to the size and center of the interference ring pattern.
