摘要
为了探究酱油光学的热透镜效应,文章以2019年全国大学生物理学术竞赛(CUPT)"酱油光学热透镜效应"这一题目为基础,研究酱油膜的浓度、厚度和激光的入射功率对热透镜效应的影响。根据温度梯度模型用Matlab软件进行理论模拟;改变酱油膜的浓度、厚度和激光的入射功率等进行多种实验,用Origin软件对实验数据进行分析,探究了酱油光学中影响热透镜效应的各种因素。研究结果表明:热透镜效应的等效焦距与激光功率、酱油浓度、膜厚均成反比。酱油的膜厚控制是使实验误差偏大的关键因素。
In order to study the thermal lens effect of soy sauce optics,this paper is based on the topic of"soy sauce optics thermal lens effect"in 2019 National University Physics Competition(CUPT).Effects of soy sauce film concentration,thickness and incident power on thermal lens effect.According to the temperature gradient model,the theoretical simulation is carried out with Matlab software.Various experiments were carried out by changing the concentration,thickness and incident power of the soy sauce film.The experimental data were analyzed with Origin software,and various factors affecting thermal lens effect in the soy sauce optics.The results show that the equivalent focal length of thermal lens effect is inversely proportional to laser power,soy sauce concentration and film thickness.The control of soy sauce film thickness is the key factor to make the experimental error larger.
