Claim 0:
1. A device for measuring a transmittance curve of a Fabry-Perot using a frequency comb light source, comprising the following components sequentially arranged in an optical path:
a single frequency pulse laser generating single frequency pulse laser;
a frequency comb laser converting received single frequency pulse laser into frequency comb laser; and
a Fabry-Perot to be detected receiving laser output from the frequency comb laser;
wherein the device further comprises a first receiving unit receiving laser from an output end of the frequency comb laser and performing component and spectrum analysis, a second receiving unit receiving laser from an output end of the Fabry-Perot to be detected and performing component and spectrum analysis, and a collimator provided with an optical aperture and arranged between the first beam splitter and the Fabry-Perot to be detected.
