Abstract

Most of the present high-speed light modulator technologies perform only binary modulation, which is not sufficient for visualization applications. A greyscale images could be obtained using temporal accumulation of binary images. This technique, known as temporal multiplexing, is applied without difficulties in applications with incoherent light (e.g. DMD video projectors). In coherent application, where the phase of the light is to take into account, temporal decomposition could introduce errors. In this paper, this point will be studied theoretically and with simulations on an optical image processor.
