Description
Atomfair-LSE489 Laser Speckle Photography Experimental Setup
Product Overview
Atomfair-LSE489 is a practical experimental device developed based on the speckle effect, belonging to the category of Fourier information optics-related experimental setups. It leverages double-exposure speckle patterns to achieve accurate testing of in-plane displacement fields on object surfaces, and can be further extended to strain, distance, and velocity measurement. Additionally, it holds promising application prospects in the detection of internal defects of objects and vibration analysis, making it an essential tool for relevant experimental research and practical testing.
Key Experimental Contents
- Capture speckle patterns in free space and imaging speckle patterns, enabling users to gain an in-depth understanding of the laser speckle phenomenon and its core characteristics.
- Master the methods of measuring in-plane displacement of objects through point-by-point analysis and full-field analysis of double-exposure speckle patterns.
