Paper Abstract

Improvements on spatial light modulation made available cost-effective correlators suitable for industrial applications. One such application field is the real-time automatic inspection of textile web. Our approaches for defect enhancement make use of wavelet and Wiener amplitude- based filtering. Simulation and optical results are presented.
