Introduction
The LEOI-30A apparatus is designed for the quantitative investigation of diffraction and interference effects. This system is capable of analyzing diffraction and interference patterns from a single-slit, multi-slit, and single-wire. It offers three options for the photo-receiving device, allowing users to select the most suitable method for data acquisition and analysis.
Option 1: A photo-cell with amplifier, which is used for manual data acquisition.
Option 2: A linear CCD for real-time data display on an oscilloscope, allowing for dynamic observation of diffraction intensity distribution.
Option 3: A linear CCD combined with a data acquisition box and software for PC-based data acquisition via USB, providing advanced features for analysis of diffraction intensity distribution.
The instruction manual contains comprehensive materials including experimental configurations, principles and step-by-step instructions. Please click Experiment Theory and Contents to find more information about this apparatus.
