Abstract: An equipment includes an excitation source ( 1 ), elements for injecting ( 2 ) an excitation signal produced by the source in an ordered bundle ( 3 ) of flexible optical fibers, elements for analyzing ( 21, 22 ) an emitted autofluorescence signal. The equipment also includes at the output of the optical fiber bundle ( 3 ) an optical head ( 4 ) designed to be placed in contact with the biological tissue ( 6 ), the optical head being equipped with optical elements adapted to cause the excitation signal output from the bundle ( 3 ) to converge into a subsurface analyzing zone ( 5 ), the same optical fiber(s) used for excitation of the bundle ( 3 ) being used for detecting the signal emitted by the subsurface analyzing zone, elements (D) placed upstream of the injection elements ( 2 ) being further provided to separate the wavelength of the excitation signal and the wavelength of the autofluorescence signal.
