A method of reproducing colored image with guided-mode resonance (GMR) gratings array is presented. It is different from traditional color impression which uses three kinds of pigment mixed to obtain various colors, but utilizes the filtering characteristics of grating to extract red, green and blue light which can be acted as three primary colors from natural light. As GMR grating shows strong resonant peak at specific wavelength as well as low sideband when illuminated by polarized light, monochromatic light with high purity can be obtained easily. In order to reduce the difficulty of actual manufacturing, only the period of grating is altered to shift the resonant position. After getting the three kinds of basic grating structures, colored image can be reappearred by distributing them. Computer simulation shows that using this method can restore colored images factually when the incident light is TE-polarized.
