HOLOGRAM
- What is a hologram?
Counter für Website
Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light.
- How to make HOLOGRAM in 2 minutes?
Step 1: Materials Required
- Plastic file
- Pencil, Scale
- Scissors
- Cellotape
- Smartphone
Step 2:Tracing the Trapezium
6cm- Other parallel side
4.5cm- Height between the parallel side
Step 3:Cutting the Trapezium From the Plastic
Tape these trapeziums together and, what you get would be exactly what we need. But, if on taping what you get is nothing like a prism but just a flat shape, it means that you did not cut the shape(s) correctly in the last step and made some mistakes which led to formation of trapezium with wrong dimensions, recheck your measurements.
