When dimensional conversion is introduced into the "ultra-multi-discrete channel optical carrier characteristics" possessed by an optical frequency comb (OFC), it becomes possible to use "dimensional conversion OFC". We have previously reported the possibility of acquiring angular spectra of surface plasmon resonance (SPR) by wavelength/angle conversion of an optical comb using a diffraction grating and using the optical comb as an "angle measure (optical protractor)". In the present study, we will attempt to acquire complex amplitude spectra of angular SPR dips using dual optical comb spectroscopy of angle-converted OFC.
