Holograms are made by using a single laser beam. The beam is then split into two beams by a special lens. That way, you get two laser beams that are exactly the same. One of those beams is the "reference beam" and is shone directly onto the film.
What is the use of a hologram?
Holograms are also used to help test different materials used in construction. Holography is a technique which enables three-dimensional images (holograms) to be made. It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording.

A monochromatic object or image has colors in shades of limited colors or hues.[clarification needed] Images using only shades of grey (with or without black and/or white) are called grayscale or black-and-white.
