We used the optical Fourrier transform to point out faults and geological irregularities in the north of France. Using mask, we eliminate linear characteristics in chosen directions and bring out those having complementary directions. We make quantative measurements of the spatial distribution of the fractures and of the direction of the isointensity curves. We establish histograms of the spatial distribution of the fractures and curves. We develop computer-generated synthetic filter holograms. We use these filters to perform mathematical operations: derivative more complex operations. We are developing an interface in the Fourrier plane from optical to numerical treatment for specific geographical application.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering.
