    Abstract: Reading light (26) is phase-modulated by a phase-modulating spatial light modulator (12), the phase-modulated reading light (26) is Fourier-transformed, and an image of the Fourier-transformed reading light is focused on an output plane (24) to form an optical pattern. In this method, 0-order light in the phase-modulated reading light (26) is blurred on the output plane (24). As the 0-order light is blurred, the luminance of the 0-order light is reduced on the output plane (24). Since the 0-order light is not blocked, the shape of the optical pattern is not limited.
