抄録

A dynamic measurement system for two-dimensional birefringence distribution is developed in order to analyze high-speed stress phenomenon. Until now, a high-speed image sensor has been applying to various applications such as mechanical motion analysis and fluorescent imaging for bio-cell based on its capability of repeating high-speed sampling. However, there are not so much reports concerning polarization application with high-speed image sensor. Although, we have already proposed various birefringence measurement methods by using rotating retarders, photo elastic modulators and liquid crystal modulators, it is still difficult to get higher sampling speed due to its limitation of mechanical movement. In this research, a new high-speed polarization sensor with pixelated micro-polarizer was developed and birefringence retardation and azimuthal angle are analyzed within sub-millisecond by phase shifting technique.
