We proposed a complex valued method based on stochastic gradient descent (SGD) and a complex valued neural network to achieve holographic imaging. We introduced an optical filter to constrain the spectrum of the complex amplitude. The experiment results show that the complex amplitude modulation can achieve a high-quality holographic display.
