- TL;DR Summary
- What is the difference between holographic paper sold in decorative shops and professional diffraction gratings? What about the difference between pearlescent decorative tape and professional dichroic mirrors?
These photos show pearlescent tape that changes color when observed from different angles. Either it's the full rainbow like in the third, fifth and seventh images I displayed here or just a few colors like in the other images, they still change color and are called "iridescent decorative tapes". How do they compare to professional diffraction gratings and professional dichroic mirrors which are more expensive? Do they work on the same principles in physics or on different principles?
