Abstract Both the axial resolution and the lateral resolution were derived from a theoretical model of optical coherence tomography technology. A miniaturized test device for measuring the light source spectrum and the numerical aperture of an optical coherence tomography system is developed to verify a commercial clinical ophthalmic optical coherence tomography equipment. The acquired axial resolution is 6.9μm, while the lateral resolution has the value of 42.3μm. The preliminary results have demonstrated that the integrated testing system could be utilized as a metrological standard device for quality control of ophthalmic OCT equipment.
