Patent ID: 7336990

Claim:
Equipment for spectroscopic analysis of autofluorescence of a biological tissue comprising: an excitation source ( 1 ), a bundle ( 3 ) constituted by a single optical fibre or a plurality of flexible optical fibres, means for injecting ( 2 ) an excitation signal produced by said excitation source into said bundle according to a useful diameter corresponding to the excitation of the single fibre, all the optical fibres in the bundle or a specific sub-group, and a means for analyzing ( 21 , 22 ) an emitted autofluorescence signal, an optical head ( 4 ) at said bundle ( 3 ) output, said optical head ( 4 ) intended to be placed in contact with the biological tissue ( 6 ), said optical head being equipped with optical means adapted for converging the excitation signal coming out of said bundle ( 3 ) into a subsurface analysis zone ( 5 ), the same optical fibre or fibres of said bundle having served for carrying the excitation signal being used for detecting the signal emitted by said subsurface analysis zone, and means (D) placed upstream of the means for injecting ( 2 ) provided for separating the excitation signal wavelength and the autofluorescence signal wavelength.
