Paper Abstract

Artificial adaptive structures are systems which react on different environmental conditions. Bridges may dampen oscillations caused by heavy wind load, while high buildings may react to static loads from snow or much more dynamic ones, such as earthquakes. To interact, adaptive systems need control systems which control the actuators by measuring sensory input parameters (length, stress, deformation etc.). We realize a system where the sensory input comes from an image based optical camera system feeding the control system. We show first results for a holographic multipoint-based system for obtaining fast and highly accurate position measurement / deformation analysis with high accuracy at multiple spatial positions.
