LESSON 5: SCIENCE AND MIXED REALITY APPLICATION

WHAT A HOLLOGRAM IS

A hologram is a three-dimensional image created by holography, a process that records and reconstructs the light eld scattered by an object.

Unlike a traditional photograph, which only captures a two-dimensional view from a single perspective, a hologram preserves the depth, parallax, and other properties of the original item. This means that as you move around a hologram, the image appears to shift and change, just as a real object would

HOW HOLLOGRAMS ARE CREATED

The process of creating a hologram involves using a laser, which produces a coherent beam of light—

meaning all the light waves have the same frequency and phase.

1.Object Beam: This beam is directed at the object

and reflects to its surface onto a recording medium, like a special photographic plate.

2. Reference Beam: This beam bypasses the object

entirely and shines directly onto the same recording medium. When the two beams meet on the recording plate, they create an interference pattern 🌀.

ASSESSMENT

1. Define what a Hologram is.
2. Explain the process of how a Hologram are created.
3. Give a difference between Mixed reality, Virtual Reality and Augmented Reality.
