Abstract :
Holographic recording, retrieving and detection of a spatially quadrature amplitude modulated signal beam, in which both the spatial intensity and phase distributions are modulated, is experimentally investigated with several measuring methods of complex amplitude of light wave. Single-shot detection technique for the spatially quadrature amplitude modulated signal beam which is inevitable for a practical perspective is also discussed.
