<P>PROBLEM TO BE SOLVED: To provide a refractive index distribution measurement system and a method of measuring refractive index distribution, capable of measuring the refractive index distribution of a subject with high accuracy. <P>SOLUTION: The refractive index distribution measurement system is provided, including a two-beam interferometer and a signal processing apparatus 90 for acquiring refractive index distribution of a subject from interference fringe images acquired by the interferometer. The interferometer includes a light source unit 10 generating coherent light, having two kinds of different wavelengths and a CPU 1 selecting one of the two kinds of wavelengths for observing the interference fringes for the respective wavelengths. The signal processing apparatus 90 uses one of the wavelengths for acquiring refractive index distribution of the subject O and the other wavelength for detecting the contour of the subject O. <P>COPYRIGHT: (C)2011,JPO&INPIT |
