Abstract :
We present a frequency-comb-based interferometric microscope. Broadband optical frequency comb (OFC) was generated using optical pulse synthesizer and non-linear fiber as the light source of interferometer. Three-dimensional surface profile was successfully observed with a resolution of 44 mum and measurement speed of 30 frame/s.
