摘要： A beam emitted from a light source is split into a probe beam that irradiates a measurement object and a reference beam that does not irradiate the measurement object. A signal beam obtained by the reflection of the probe beam is split into first and second split signal beams, which are mutually orthogonal polarized components. The first split signal beam and the reference beam are inputted to a first coherence optical system to cause the beams to interfere with each other to generate at least three coherence beams differing in phasic relationship. The second split signal beam and the reference beam are inputted to a second coherence optical system to cause the beams to interfere with each other to generate at least three coherence beams differing in phasic relationship. The coherence beams are then detected.

摘要： A luminous flux including laser light of different wavelengths outgoing from a light source unit is split into two luminous fluxes, the first luminous flux is focused on a sample with an objective lens, and the second luminous flux functions as reference light without radiating it onto the sample. Signal light reflected from the sample and the reference light are multiplexed by a polarized beam splitter and are made to interfere on four photodetectors out of phase in a photodetection unit. A signal processing unit acquires the optical axis distribution of an object of examination in the sample by operating using the outputs of the plural photodetectors for input every wavelength, acquiring a detection signal and calculating the ratio of detection signals of different wavelengths every position in the sample.
