水下偏振成像技术实验教学化的探索

Exploration on the teaching of underwater polarization imaging technology experiment

为提高光的偏振现象实验的应用性和拓展性,设计了基于水下偏振成像技术的教学实验.以观察光的起偏和检偏现象为目标,搭建水下偏振成像实验平台,基于斯托克斯理论,采集浑浊水体中目标的偏振子图像,计算偏振度,然后通过图像处理软件获取最终清晰成像结果.该实验综合了光的偏振特性相关知识和实际应用方法,实验效果明显,可操作性强,通过实验能够有效加深学生对该知识点的理解.

An experiment based on underwater polarization imaging was designed to enhance full utilization and expansion of polarization.It started from observing polarizing and analyzing polarization phenomenon to get the students familiar with the experiment.Then based on the Stokes theory,the following steps could be completed,including setting up experiment platform,capturing polarization images in turbid water and calculating degree of polarization.The final clear images were obtained by importing the captured images into a software.This experiment was featured by the design involving the application of polarization,which was highly operable and could also be extended.Students would get deeper understanding of relative theory from the experiment.
