ABSTRACT:
A compensation table for compensating interference signal obtained by OCT measurement is generated easily. When a reflection body interference signal is obtained by OCT measurement, the reflection body interference signal is compensated by a compensation table (Formula (1)) to obtain an evaluation output signal. Then, a spectrum of the evaluation output signal is calculated to obtain an evaluation value of the spectrum. Thereafter, a model coefficient is updated such that the evaluation value becomes small.
