ABSTRACT:
A tunable light source10for varying emission wavelength periodically and an optical interferometer are used. A reflector is disposed at a measurement position, a light interference signal is A/D converted at a regular time interval, and data numbers at timing giving peak and bottom are calculated according to a least-squares method. Based on this, an approximate equation is calculated according to polynomial approximation and a sequence including the number of exponentiation of 2 and converting the data number at a regular frequency interval is calculated. Then, by disposing a measured target at the measurement position, calculating the necessary number of pieces of data for FFT from measured data at each timing according to straight-line approximation and Fourier transforming a light beat signal obtained by an optical interferometer at regular frequency interval, a tomogram having high resolution and high sensitivity can be acquired.
