An enhanced Fourier-domain optical coherence tomography (EOCT) based on spectrum correction technique is developed and employed in non-contact measurement of structural vibration and thermal deformation, and real-time calibration of PZT actuators. The EOCT system used a broadband CCD-based spectrometer and a short-coherence white light source. Due to the broadband of the spectrometer and light source, the system provided high robust performance with an excellent measurement resolution of 0.9. Because of the energy leakage effect of FFT, a spectrum correction technique was employed to enhance the resolution of the EOCT system. The detection resolution for vibration and thermal deformation measurement could be up to 0.1. From the experimental results, the self-developed EOCT has great potential applications in non-contact structural vibration, thermal deformation measurement, and real-time calibration of PZT actuators
