A method includes performing first and second measurements with a turbid medium to be examined placed in a receiving volume of a device for examining the interior of turbid media. The second measurement is performed after a time interval has passed after the first measurement. Each of the first and second measurements includes subsequently irradiating the turbid medium with light from a light source from a plurality of different source positions and detecting light emanating from the turbid medium in a plurality of different detection positions for each source position, and storing the detected values as measurement results. The method also includes detecting inhomogeneities in the interior of the turbid medium by using the measurement results of one of the first and second measurements as a reference and the measurement results of the respective other of the first and second measurements to determine deviations from the reference.
