In this research, we introduce a new system based on the ghost imaging, for measuring the surface profile of an object using optical frequency comb laser and a single-pixel camera. The optical frequency comb laser was used to record the relative phase of the object precisely whilst the ghost imaging technique was applied to reconstruct the object's profile. The effect of using a mask on the parameters such as number of object point, number of measurements and sparse number related to the complexity of the object for reconstruction was studied by a simulation. The performance of the system strongly depends on the design of the mask. The random mask and the Hadamard mask were used to estimate the performances in the optical frequency comb profilometry.
