Frequently asked questions
What is diffraction efficiency in holograms?
Diffraction efficiency measures the percentage of incident light intensity that gets diffracted into a specific order, indicating hologram performance quality.
How does wavelength affect hologram diffraction?
Different wavelengths diffract at different angles through the same hologram, with shorter wavelengths producing smaller diffraction angles than longer ones.
What are diffraction orders in holographic gratings?
Diffraction orders represent different angles where constructive interference occurs, labeled as 0, ±1, ±2, etc., with higher orders at larger angles.
