Abstract: “We present a method that significantly improves the quality of the optically reconstructed complex amplitude from a spatial light modulator (SLM). This method is based on applying a digital pre-filtering of the SLM’s encoded distribution to compensate the signal distortion caused by the SLM’s finite pixel size. In this approach the complex transmittance is changed in such a way that it compensates the modulation in the Fourier plane. The basic principle of this technique and its experimental verification are described.”
