Abstract

Coupling efficiency equation of optical coherence tomography system with gradient refractive index rod lens is established and discussed theoretically and experimentally. The experimental result is consistent with the theoretical result. The higher coupling efficiency of optical coherence tomography system can be obtained if the θ which is the angle between mirror and y axis should be smaller than 0.5 degree.
