A method for the non-destructive inspection of a part made from an organic-matrix composite material includes the steps of: a) carrying out a surface inspection of the part by Fourier transform infrared spectroscopy, b) if step a) reveals a defect, carrying out in-depth inspections of the organic-matrix composite material according to two complementary ultrasound techniques. The processing subsystem is further responsive to a change in rate of receipt of the data to modify the visualization output with one or more other data vectors corresponding to a second portion of the data stream as a function of eigenspace defined with the group of data vectors. A spectral power distribution of a direct irradiance of a current ambient illuminant is cyclically and repetitively estimated by using a measurement of the spectral power distribution of the direct irradiance of the current ambient illuminant. The system also includes a waveform module that is configured to obtain physiological signals as a function of time.
