| 摘 要： | 激光诱导荧光法是近年来测试油膜厚度的新方法，分析了采用此法将光路暴露于空气中的油膜厚度测试系统的不足之处，研制出光纤代的油膜厚度探测系统，通过上述两种测试系统的对比实验，得出新型光纤式油膜厚度探测系统具有易于拆装、移动方便、灵敏度高且有测试的连续性和稳定性等特点，弥补了现有方法的不足。

| Abstract: | Laser induced fluorescence technique is one of the effective methods to measure the oil film in recent years. The paper gives the drawbacks of the existing measuring system using laser induced fluorescence technique, which exposes laser rays in the air. It presents an improved system using fiber optic. The comparison test shows the increasing signal to noise ratio using new diagnostics system.The new system is characterized by its easy installation, portable and compact structure, and increasing signal to noise ratio. |
