We developed a technique for constructing light diffusing devices comprised of a flexible shape memory polymer (SMP) cylindrical diffuser attached to the tip of an optical fiber. The devices are fabricated by casting an SMP rod over the cleaved tip of an optical fiber and media blasting the SMP rod to create a light diffusing surface. The axial and polar emission profiles and circumferential (azimuthal) uniformity are characterized for various blasting pressures, nozzle-to-sample distances, and nozzle translation speeds. The diffusers are generally strongly forward-directed and consistently withstand over 8 W of incident IR laser light without suffering damage when immersed in water. These devices are suitable for various endoluminal and interstitial biomedical applications.

我们开发了一种用于构造光漫射设备的技术,该设备由连接到光纤尖端的柔性形状记忆聚合物 (SMP) 圆柱形漫射器组成。通过在光纤的劈裂尖端上浇铸SMP棒,并对SMP棒进行介质爆破以产生光漫射表面来制造设备。轴向和极性发射轮廓以及周向 (方位) 均匀性的特征在于各种爆破压力,喷嘴到样品的距离以及喷嘴的平移速度。扩散器通常是强烈的正向方向,并且在浸入水中时始终承受超过8 W的入射IR激光而不会受到损坏。这些设备适用于各种腔内和间隙生物医学应用。
