摘　　要：直型和折叠型衰荡光腔相结合技术精确检测了一组平面ＣＯＩＬ高反腔镜在１．３１５μｍ的实际反射率。实验测得ＣＯＩＬ平面高反腔镜反射率高达９９．９３１％，测量精度为１０＾－５，本技术对镜片的反射角度，基底材料透光性能及尺寸无特殊要求，可由反射率相对较低的腔镜，测量高反射率率镜片。High reflective COIL mirrors at 1.315 m have been precisely measuredvia using cavity ring-down technique by combining straight and folded cavities.Experimental results show that the reflectivity is as high as 99-931% with measuringaccuracy of 10-s. Mirrors to be measured can be opaque with any size at any angleof reflection. A cavity with lower reflectivity mirrors is used to measure the higherreflectivity mirrors .
