SYSTEM AND METHOD FOR MEASURING PROPERTIES OF A FORCE ACTING ON A FLUID ELEMENT

摘要

A system and a method for measuring properties of a force acting on a fluid element (10) are provided. The fluid element contains a first fluid (A) and a second fluid (B) that are non-miscible. When a force acts on the element and deforms a meniscus (14) between the fluids, the symmetric and asymmetric wavefront characteristics of the light beam passing the fluid lens are changed. By measuring these characteristics the orientation and/or the strength of the force and other quantities related thereto can be determined.
