A method for recording images of small particles to detect cracking includes
feeding
particle samples to a place for image recording, illumination a particle sample
from at least two directions simultaneously, the illumination occurring with different
light wavelengths for each direction, recording partial images of the illuminated
particle in different channels, which are sensitive to different wavelengths, and
comparing the different partial images to analyze the particle sample. Each partial
image shows the particle sample illuminated from one direction by the channel recording
only one of the different light wavelengths.
