LBTEK's Fourier Optics Teaching System Kit includes components, software, and teaching materials, covering optical characteristics and imaging techniques, suitable for teaching, experiments, and classroom scenarios. The Fourier Optics Teaching System is a modern teaching tool designed for majors such as optics, optoelectronic information science and engineering, and applied physics. Through a teaching model combining theoretical explanation and hands-on experimentation, it helps students understand the abstract mathematical principles and physical essence of Fourier optics, serving as a key educational bridge between fundamental optics and modern optical applications. In this teaching system, the chrome-plated glass target used for observation is engraved with eleven different patterns. A beam splitter and lenses project the patterns from the Fourier plane onto a screen for direct viewing. Students can alter the patterns in the Fourier plane using chrome-plated glass masks, rotating slits, or apertures to achieve various optical effects.
