Soft-light hologram

From Fybertech Wiki

The term "soft-light hologram" is used to refer to a formation of light and/or energy to generate the representation of an object. Matter can freely pass through a soft-light hologram, due to its non-materialistic nature.

An example of such usage is explained in Fybertech: The De Novo Project, where it is used to masked the entrance to a mountain laboratory with an artificial rock wall.
