摘要
光学技术在通信、医疗、军事等领域有着广泛应用,而且培养具有创新思维和实践能力的复合型人才是光学技术可持续发展的关键。当前,光学课程侧重于理论知识的传授,而在较大程度上缺乏理论与实践内在联系的讨论,制约了高水平光学人才的培养。为提升创新思维和工程实践能力的培养水平,应适当将工程案例和科学前沿引入到光学课程的基础理论教学中。在应用实践中,各类噪声影响乃至决定着光学装置的性能。本文着重讨论噪声对光学干涉特性的内在影响,探究了散射光场的聚焦。研究发现,尽管散射光的聚焦在原理上起源于光学多路径干涉,但是聚焦效果和实验装置中的各种噪声密切相关。将散射光聚焦及其噪声因素分析引入到课堂教学,有助于启发学生从实际应用出发去理解光学理论,从而培养学生的工程创新能力。
Optical technology has a wide range of applications in various fields such as communication,medicine and military,while the cultivation of compound talents with innovative thinking and practical ability is the key to its sustainable de-velopment.Currently,optical courses often emphasize on theoretical knowledge,but are lack of discussions on the inherent link between theory and practice to a great extent.This deficiency hinders the cultivation of high-level optical talents.In order to enhance students’ability of innovative thinking and engineering practice,it is desired to introduce engineering cases and scientific frontiers into the teaching of basic theories in optics courses.In practices,various noises affect or even determine the performance of optical instruments.Therefore,this article focuses on the inherent impact of noise on optical interference prop-erties,and explores the focus of scattered light filed.It is found that although the focusing of scattered light originates from op-tical multi-path interference in principle,but its practical manifestation is closely related to the presence of various noises of experimental setup.Introducing the analysis of scattered light’s focusing along with its noise factors into teaching helps to in-spire students to comprehend the optical theory from practical applications,thus cultivating their engineering innovation ability.
