Title: Optical characteristic measuring apparatus and method therefor, program and recording medium having program recorded thereon
Inventor: YAMASHITA TOMOTAKE
IPC: G01M11/02
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To enhance the measuring accuracy of a group delay time or the like by increasing the intensity modulation frequency of light incident on an optical fiber. SOLUTION: A frequency setting part 32 sets intensity modulation frequency to second frequency f2 exceeding first frequency f1 so as to bring the absolute value of the difference between the phase difference of a transmission signal A and a intensity modulating signal R immediately before changing the wavelength of incident light, and the phase difference of the transmission signal A and the intensity modulating signal R immediately after changing the wavelength of incident light to 180 deg. or less. Therefore, the measuring accuracy of the group delay time or the like of the optical fiber 40 can be enhanced.  In this case, the measuring result of a phase comparator 70 is largely different from phase difference according to circumstances but there is no problem because the group delay time or the like in the case of the second frequency f2 is corrected on the basis of the phase difference, in such a case that the intensity modulation frequency is the first frequency f1 by a correction part 90.
