  • Published:
Archiv für Mikrobiologie Aims and scope Submit manuscript

Summary

The use of Fourier transform coherent optical techniques in the pattern recognition of microscopic algae, i.e., diatoms, is described. The results of the construction of complex-valued filters for diatoms and their usefulness in algal identification are presented. Some general applications to water pollution monitoring and control are discussed.
