Paper Abstract

We present a novel liquid viscosity measuring approach based on the optical trapping technology. We put a “test-micro-particle” enclosed in a confined space built by a quartz capillary tube and two opposite-inserted optical fibers to construct the test cell. In order to make the test cell have the ability of auto-ready and easy-reset, we design and fabricate a special notch-shape in the ends of two fibers. This novel approach provides a new probably development direction for the optical tweezers technology applying on the sensing and measuring fields, and solve the optical tweezers measurement repeatability problems.
