Application of Hologram Technology
This is a question regarding the technology of the hologram. Can two overlaying images be applied to a card similar to a credit card? If so, can one be seen by the naked eye and the other only by the use of special glasses?
Thank you

There are special Kinds of hologramms, called hidden, which can only be seen with special lightsources shining at them. These kind of hologramms can be overlaid by a "standard" hologramm, which can be seen using normal light.

Thinking on holograms, can two or three beams of possibly different types of lights be projected to a point in space and where this beams of light converge create an image or a ball of light at that point?
