Abstract :
According to the characteristics of forming and diffracting rainbow hologram, this paper presents a mathematical imaging model inhibiting diffraction effect for special printings. It makes the incident angles of light on the imaging surface range from - intensity of incident light evenly distributes on the imaging surface so that the dispersion effect of diffraction grating is effectively inhibited, which helps to the imaging for printed matters of laser rainbow holographic. Based on this model, a dome light source is proposed specially for holographic printed matter imaging. Experiments show that the dome light source based on the model inhibits diffraction effect well on laser rainbow holographic printings, which effectively solves the interference problem for CCD camera imaging caused by laser rainbow hologram in white light.
