An interferometer is a scientific instrument that can measure the properties of light waves. It is commonly used in areas such as astronomy, physics, and engineering. There are several synonyms for the word interferometer, such as wavefront analyzer, optical imager, and optical interferometer. A wavefront analyzer is an instrument that analyzes the shape of a wavefront, while an optical imager creates an image by analyzing the interference patterns of light waves. An optical interferometer is an instrument that uses a beam splitter and other optical components to interfere light waves, enabling measurements to be made of their properties. These synonyms are common terms in the scientific community and may be used interchangeably in the context of scientific research.
