Optical Resolution Model

written by Fu-Kwun Hwang
edited by Robert Mohr

The EJS Optical Resolution model computes the image from two point sources as seen through a circular aperture such as a telescope or a microscope. The simulation allows the user to vary the distance between the light sources and the diameter of the aperture, as well as the intensity of the light source.

The Optical Resolution model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).

Optical Resolution Model:

Is the Basis For Exploring the Optical Resolution Model for understanding Rayleigh criterion

The Optical Resolution Model, originally created by Fu-Kwun Hwang and edited by Robert Mohr and now converted to EJS Javascript 6.1 by lookang, provides a powerful tool for understanding how two point sources of light are resolved when viewed through a circular aperture. This simulation mirrors real-world instruments like telescopes or microscopes, where diffraction plays a crucial role in determining the clarity and separation of objects. The model, now converted from EJS Java to EJS JavaScript, retains its core functionality while allowing broader accessibility on modern web platforms.
