Frequency scanning spectroscopy of optical frequency comb with high-resolution on an absolute frequency axis

We propose high resolution spectroscopy based on a single-sideband optical modulator and an optical frequency comb technology. It has been confirmed experimentally that the spectral resolution and the frequency measurement range was digit of 1 MHz (10
^-5
nm) and 1 THz (10 nm), which is corresponding to the comb bandwidth, respectively.
