Abstract

In this study, a duplex scanning optical delay line is implemented and characterized for optical coherence tomography. The reference and sample arms in Michelson interferometer are simultaneously scanned by use of two identical piezoelectric transducers (PZT). It is obtained that scanning range, thermal drift, repeatability, and axial scanning velocity of duplex optical scanning delay line are distinctly superior to those of single scanning optical delay line.
