In recent years, the HDS is expected as an optical recording medium, and a spatial quadrature amplitude modulation method for realizing a large capacity recording has been widely studied. We are trying to detect the complex amplitude of the spatial quadrature amplitude modulated signal beam by the transport of intensity equation method only from the diffraction intensity images of the light wave without using the interferometric measurement. In this paper, we propose a method for single-shot capture of multiple diffraction intensity images necessary for phase detection using a camera with a micropolarizer array and using it for signal beam detection by the transport of intensity equation.
