摘要
针对界面凝胶法制作的梯度折射率塑料光纤预制棒,提出了一种利用预制棒成像测量其折射率分布的方法,它是一种非破坏性测量。实验结果表明这种测量方法简单有效。
An imaging method for measurement of refractive-index profiles in graded-index POF preforms which are fabricated by interfacial-gel technique is proposed. It is a nondestructive measurement. The experimental results show that this method is simple and effective.
