摘　　要：通过分析眼科光学相干层析设备的成像分辨率理论计算模型,设计并研制了一套用于测量其光源光谱和系统数值孔径的小型化检测装置。针对一台商业化的临床在用眼科光学相干层析设备,通过对其关键参数的测量,得到该设备的纵向分辨率为6.9μm,横向分辨率为42.3μm。该检测装置未来可作为眼科光学相干层析设备的质控与计量器具。Both the axial resolution and the lateral resolution were derived from a theoretical model of optical coherence tomoga-aphy 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 6.9 μm, while the lateral resolution has the value of 42.3 μm. The preliminary, results have demonstrated that the integrated testing system could he utilized as a metrological standard device for quality control of ophthalmic OCT equipment.
