<p>A method of operating a pixellated spatial light modulator (SLM) 350 to display data representing a polychromatic image, wherein a first subset of modulator pixels are allocated to first colour image information and a second subset of SLM pixels are allocated to second colour information. The numbers of pixels in the first and second subsets are determined by the respective first and second color wavelengths, to which the human eye has differing sensitivities. Also disclosed is a projector forming a 2D polychromatic image, using the same method of allocation of amount of pixels based on colour wavelength, and a liquid crystal on silicon (LCOS) SLM to display Fourier transform (FT) data. Based on different colours, different pixel subsets comprise differing, greater or lesser, pixel numbers. Phase-only, holographic diffractive image data (e.g., based on the Gerchberg-Saxton, FIENUP, FIDOC, direct binary search or genetic algorithms) may be displayed, and the SLM may modulate to apply a phase delay to incident light. Fourier data for plural colours may be displayed simultaneously on the SLM. The method cen be applied to a head-up display (HUD), 300.</p> |
