Wave optics teaching method and device based on light field screen projection

Abstract

The invention discloses a wave optics teaching method based on light field screen projection. The method comprises the following steps: S1, selecting a wave optics experiment module for demonstrationexperiment through a control module according to the course content; S2, projecting a fluctuation light field of the fluctuation optical experiment module and an image of a measurement scale of the experiment result measurement module to an observation screen by using a projection module; and S3, obtaining experimental data through an observation screen, and comparing the experimental data with the theoretical numerical value. According to the invention, a plurality of wave optical experiments can be projected and demonstrated without time-consuming and labor-consuming optical path adjustment,and the measuring scale can be synchronously projected to complete the measurement of experimental results, thereby meeting the watching and actual understanding of students, and improving the teaching result and quality.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a wave optics teaching method and teaching device based on light field projection. Background technique [0002] Light is an electromagnetic wave with wave-particle duality. The study of wave optics theory has deepened people's understanding of the nature of light, and has a strong guiding role in actual production and application. However, the teaching content of wave optics is relatively complex and abstract, and students often find it difficult during the learning process. When teachers give lectures in class, the focus is generally on conceptual elaboration and theoretical derivation, sometimes supplemented by brief picture illustrations. However, these teaching methods It is difficult for students to establish a deep understanding of wave optics knowledge, and it is easy to make students feel boring. [0003] In recent years, with the rapid development of compu...

Problems solved by technology

Generally speaking, to complete the demonstration of these experiments, multiple sets of optical paths need to be built, which is time-consuming and laborious, and the limited teaching hours of wave optics do not allow teachers to complete the construction and adjustment of the demonstration optical paths in each class.

In addition, although there are some multi-functional wave optics comprehensive testing instruments or integrated wave optics experimental benches that can complete multiple wave optics experiments with one set of instruments, such instruments are often suitable for experimental teaching and cannot satisfy multiple students in the classroom. At the same time, the demand for long-distance viewing is not suitable for classroom teaching demonstrations
