Abstract
A high speed motion detection technique using SS-OCT system is demonstrated. Acquired OCT signal from high speed reflector result in producing artifacts like axial position shifts and broadening of the OCT signal in final processed images. A methodology using forward and backward wavelength sweeps of swept source laser to correct these artifacts is proposed. Analysis of phase changes of interferograms recorded with bi-directional laser sweeps at high sweep rates can be used to determine the true trajectory of the fast moving object. This technique also helps in monitoring velocity of the object exceeding the velocity range set by the acquisition speed of the OCT system.
