使用說明
以波動光學為基礎,模擬光在孔徑後因繞射與干涉形成的光強度分布。
支援單一、雙光源以及 10、 30 個隨機分布光源,可觀察空間相干性對干涉條紋的影響。
可自由調整光源間距、相對角度與位置偏移,即時觀察干涉圖樣的變化。
支援圓形孔徑與長方形孔徑,並可設定孔徑尺寸與旋轉角度。
可選擇單孔徑或雙孔徑,比較單孔繞射與雙孔干涉的差異。
同時呈現二維平面光強度分布與一維剖面光強度曲線,強化定量理解。
剖面位置可即時調整或直接點擊圖像選取,方便觀察條紋強度變化。
支援單色光與白光模式,白光模式以多波長疊加呈現彩色干涉結果。
提供完整的幾何示意圖,清楚顯示光源平面、孔徑平面與成像平面之間的關係。
純瀏覽器即時運算與互動,並支援多語言,適合教學與探究使用。
User Guide
Based on wave optics, this tool simulates the light intensity distribution formed by diffraction and interference after light passes through an aperture.
It supports single and double light sources, as well as 10 or 30 randomly distributed sources, allowing observation of how spatial coherence affects interference fringes.
The spacing between light sources, their relative angles, and positional offsets can be freely adjusted, enabling real-time observation of changes in the interference pattern.
Both circular and rectangular apertures are supported, with configurable aperture size and rotation angle.
Users can choose between a single aperture or a double aperture to compare single-aperture diffraction with double-aperture interference.
The system simultaneously displays the two-dimensional light intensity distribution and a one-dimensional cross-sectional intensity profile, enhancing quantitative understanding.
The cross-section position can be adjusted in real time or selected directly by clicking on the image, making it easy to observe variations in fringe intensity.
Both monochromatic and white-light modes are supported; in white-light mode, multiple wavelengths are superimposed to produce colored interference patterns.
A complete geometric schematic is provided, clearly showing the relationships among the source plane, aperture plane, and imaging plane.
All computations and interactions run in real time directly in the browser, with multilingual support, making it suitable for teaching and exploratory learning.
