Study on Grating Constant of Matte Light Pillar Holographic Materials

摘要

In order to study the grating constant of the matte light pillar holographic materials, the X-Rite MA68 Ⅱ multi-angle spectrophotometer was used to measure the spectral energies of the matte light pillar holographic materials. The reflective and diffractive spectral energies perpendicular to the direction of the light pillar and along the direction of the light pillar in the visible light range at five angles (15°, 25°, 45°, 75°, 110°) were analyzed with the grating equation. It was found that the grating constant of the matte light pillar holographic materials is in a range rather than that of the rainbow light pillar holographic materials which had fixed value, which will only cause the lightness variations significantly.
