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.

What is the maximum measurable in-plane displacement range of the Atomfair-LSE489 using double-exposure speckle photography?
The Atomfair-LSE489 does not specify a maximum measurable displacement range in its product description. The system is designed for accurate in-plane displacement measurement via double-exposure speckle patterns, but the range depends on the optical configuration and the specific experimental setup. For precise range specifications, please contact the manufacturer at inquiry@atomfair.com.
The Atomfair-LSE489 is a helium-neon laser-based experimental setup for double-exposure speckle photography, enabling in-plane displacement measurement via point-by-point and full-field analysis. Its 632.8nm TEM00 laser and included optical components support both free-space and imaging speckle capture, though manual timing and reference-only specifications require user calibration.
Positive
- Dual-mode speckle capture: Supports both free-space and imaging speckle pattern acquisition, enabling comprehensive study of laser speckle phenomena and core characteristics.
- Complete optical train included: Comes with beam expander (f=4.5mm), collimator (f=50mm), and ground glass (80x80mm), providing all essential components for immediate experimental setup.
Trade-offs
- Manual exposure timing: The exposure timer is manually timed, requiring operator precision and consistency to achieve reliable double-exposure speckle patterns.
- Reference-only specifications: Stated configurations are for reference only; actual specifications may vary per the packing list, necessitating verification before critical experiments.
