In an OCT sensing system, the optical coherence length of the light source determines the spatial resolution, which is within the range of tens of micrometers. In this paper, by removing high frequency noise with average operation and fitting the measured discrete sampled data with a continuous function, the theoretical resolution can be improved. The experimental results obtained show the short term repeatability to be better than 0.4 μm after signal processing.
