Light Analyzer: An Open Source Physics Data Logger

The Light Analyzer is an innovative application designed to capture and analyze images from your device's front or back camera, or from files you upload. This tool is particularly useful for logging physical data related to light spectra and other wave-related phenomena.

Features and Versions

• HTML5 Version: The app is built using HTML5 technology, making it accessible across various platforms.
• v21: Updated to Ionic 4, this version includes a "compare" button that allows users to compare their data with real-world data available on the internet.
• v13: This iteration automatically asks for camera permissions and supports a 3D-printed attachment for the back camera. Users can take photos of light spectra and analyze them using the ruler feature.
• v6: The app requires a diffraction grating and a light source like a laser pointer. It also supports both back and front cameras and includes features like auto-find light and calibration of known diffraction orders.
• Current Version 4: Some devices may need manual permission settings for the camera, but restarting the app usually resolves this issue.

Usage and Physical Apparatus

To use the app effectively, you will need:

• A diffraction grating.
• A light source, such as a multi-purpose laser pointer.
• A smartphone with the app installed or a laptop with a camera.

The app is designed to work seamlessly with these components and provides detailed instructions for optimal setup and usage.

About the Project

The Light Analyzer is an open-source physics simulation developed in Singapore. The code is based on work by Félix Jesús García Clemente and is part of a broader educational initiative supported by the Ministry of Education (MOE) and the National Institute of Education (NIE) in Singapore.

Acknowledgements

The development of this app would not have been possible without the contributions of numerous experts in the Open Source Physics community, including Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, and many others. Their insights and support have been invaluable.
