FAQ
Frequently Asked Questions
In digital signal processing and computer graphics, the moire effect is a specific, often highly visible, manifestation of aliasing—the distortion caused by undersampling a signal.
Rarely. It is generally an unwanted artifact. However, in scientific and engineering fields (moiré interferometry), deliberately created moire patterns are used to measure strain, displacement, and surface contours.
The most standard pronunciation is /mwɑːˈreɪ/, similar to 'mwah-RAY'. The 'oi' is often pronounced like 'wa'. In American English, /ˈmɔɪreɪ/ (like 'MOY-ray') is also heard.
In English, it is often omitted ('moire'), especially in technical writing. The accented form ('moiré') is more common in British English and when referring to the fabric. Both are acceptable.
