The discriminating capability of a coherent optical processor in identifying diatom species was tested using 25 species selected by diatom taxonomists. A 25 × 25 matrix of auto‐ and cross‐correlations was used for this purpose. In no case did cross‐correlation signals approach the intensity of auto‐correlations indicating that false identifications were extremely improbable. Shape and height differences of the cross‐correlation signals can be attributed to variations in diatom shapes, sizes, and cell wall morphology.
