Diffraction is a property of all waves and something that happens when a wave hits an object or passes through an aperture.
|
||
|
|
This applies to waves in a pond, sound waves, or light waves

|
- this gives CDs their amazing shiny culture
|
||
|
|
- as well as opals their textured shine
|
||
|
|
- as well as atoms and molecules
|
||
|
|
- the reason why nearby stars also have their distinct patterns

When you shine light through a series of lines it becomes a working diffraction grating.
|
||
|
|
|
||
|
|
Adding more diffraction gratings adds more spikes. Diffraction comes from distance between the lines and the angle.

Instead of controlling RGB values like a normal screen, each pixel instead adjusts its index of refraction.

|
Refractive index - a measure of how much light slows down when it enters that material
|
||
|
|
|
||
|
|
the higher refractive index, the more light is slowed relative to light in a vacuum.
