Abstract: A wavelength-variable light source is configured to emit a light with a wavelength (?), which is variable within a scan width (??). An interferometer has a coherent length (?L), which is determinable from (??) and (?). A controller determines an appropriate magnitude of the scan width (??) while a CCD camera captures a fringe image in an exposure time (Te), which is set longer than a time for wavelength scanning.

Abstract: An interferometer comprises a wavelength-variable light source. A reference light and a measurement light are synthesized, and the synthesized light is split into a plurality of split lights. A certain phase difference is provided between the split lights through phase shifting optical members. A plurality of interference fringe images formed by the phase-shifted split lights are captured at an imaging unit. Biases, amplitudes and the amounts of phase shift of the interference fringes formed by the plurality of split lights are calculated, based on interference fringe intensities of the imaged interference fringes, which are obtained by disposing a calibrating substrate instead of the measuring object varying the wavelength of the emitted light to plural values, and operating the imaging unit to capture a plurality of images of interference fringes obtained by the split lights.
