摘    要:为检测透明容器内表面是否存在污染物,建立了基于容器壁内表面反射的低相干光干涉测量系统。实验采用宽带低相干半导体激光光源和改进的迈克尔逊干涉仪。将测量臂光路对准透明容器,并调节参考臂的光程,使容器内表面反射光的光程与参考臂反射光的光程相等,并出现干涉现象,捕捉并记录此动态干涉信号。经MATLAB软件处理并提取此信号,根据干涉光强度的不同即可辨别透明容器内是否存在污染物。该检测法可为生物医学、食品质检等领域检测透明容器内表面污染物提供一种方便快捷的新方法。

关 键 词:污染物  内表面  低相干光干涉

Abstract:In order to detect the existence of contaminants in inner surface of the transparent vessel, an optical low coherence interference measurement system based on the reflection of the inner surface of the vessel is established. Broadband low coherence laser diode light source and improved Michelson interferometer are adopted. The optical path of the measuring arm is aligned with the transparent vessel, and then optical path of the reference arm is adjusted. When the optical path from the wall of the inner surface in the vessel is equal to the optical path from the reference arm, there is interference. The dynamic interference signal can be captured and recorded. The signal is processed and extracted by using MATLAB software. According to the difference of the intensity of the interference signal, we can distinguish whether there is contaminant in the transparent vessel. This paper can provide a real-time and novel method for detecting contaminants in the transparent vessels in biomedical, food and other fields.
Keywords:contaminants  inner surface  optical low coherence interference
