Abstract

A fiber-optic data-input device, called 'data-cube', was developed for measuring strain induced in elastic bars by bending. The data cube consists of three double-polarization Michelson interferometers mounted on separate panels in a cubic housing, with interferometers used as optical strain gauges for measuring the surface strain. Two interferometers serve as force or displacement sensors for manual input commands, while the third measures the orientation of the cube with respect to the gravity vector by means of an accelerometer arrangement. The measured characteristics of strain via bending induced by an external force were compared with the theoretical relationship.
