Abstract :
We have developed a new high-speed and sensitive 2-Dimensional automatic measurement system with which the birefringence vector distribution corresponding to the internal stress distribution in a PMMA disk can be measured. The results obtained in a series of this experiment are compared with that obtained using the finite element calculation method
