采用两积分球系统测量了兔动脉和静脉对波长为４４１６ ｎｍ 的 Ｈｅ Ｃｄ 激光的反射和透射特性，并据测量数据计算和分析了兔动脉和静脉对该波长激光吸收系数及光学穿透深度。结果表明，兔动脉和静脉的漫反射率和透射率有明显差别；和静脉比较，动脉的漫反射明显大于静脉，但动脉对 Ｈｅ Ｃｄ 激光的吸收系数和静脉对该激光的吸收系数相差不大，该波长的 Ｈｅ Ｃｄ 激光在动脉和静脉的光学穿透深度非常相近。
Two-point sphere system was used to measure the reflection and transmission properties of rabbit artery and vein to He Cd laser with a wavelength of 4416 nm. According to the measurement data, the laser absorption coefficient and optical penetration of rabbit artery and vein were calculated and analyzed Through the depth. The results showed that the diffuse reflectivity and transmissivity of rabbit arteries and veins were significantly different. Compared with the veins, the diffuse reflection of arteries was obviously larger than that of the veins. However, the absorption coefficient of HeCD laser and the absorption coefficient of veins to this laser were not different Large, this wavelength He Cd laser in the arteries and veins optical penetration depth are very similar.
