CONSTITUTION: A vibration-insensitive interferometer comprises a light source(100), a light transmission part(200), a continuous phase scanning part(300), and a high speed camera(400).

The continuous phase scanning part scans the reference beam split by the light transmission part with a continuous phase scanning method. The high speed camera acquires the interference pattern created by the measurement beam irradiated by the light transmission part and the reference beam irradiated by the continuous phase scanning part.

When a light source incident to the diffraction grating is resolved into several diffraction lights, one of them having a diffraction element is selected as a reference light, and other part having the diffraction element or another light having other diffraction element is selected as a light directing to an object to be measured. The light directing to the object to be measured is reflected from the object and is incident to the diffraction grating and then diffracted, and object lights made by the diffraction generates the reference light and an interference pattern. When the diffraction grating is moved in a longitudinal direction, the object light or the reference light is phase-shifted, a number of interference patterns are obtained, and the interference patterns are analyzed to obtain a shape of the measured object.
