This paper describes a new "3D-MUSTERDS-Three Dimensional Multi-Point Sternum Displacement Sensing System". The aim is to measure chest deflections of anthropomorphic dummy to be used in vehicle collision tests. The 3D-MUSTERDS consists of: (1) an optical position sensing system. This sensing system consists of a light emitting diodes (LEDs) which is installed on the sternum, and a position sensing detector (PSD) cameras installed on the thoracic spine. It is placed in the rib cage; and (2) an external system to calculate and control the coordinates. This new system is characterized by the ease with which it can be applied to the chest of Hybrid m dummy. It is also verified that its frequency response and the impact resistance are excellent, with sufficient capabilities as a practical system for the measurement of the sternum (chest) deflections in normal collision tests. The paper also describes some examples of the applications of the system. (A)
