Reflection on such housing walls would lead to scattered light, which reduces the contrast of the hologram element and the quality of the illumination thereof deteriorates. In particular, when the reflected scattered light strikes the hologram element at a reconstruction angle, this can lead to a diffuse hologram image or holographic luminous image.
