Apparatus for the non-destructive testing of the integrity and/or suitability of sealed packagings

An apparatus (10) for the non-destructive testing of the integrity and/or suitability of sealed packagings (100) having at least one portion (111, 121) at least partially optically transparent, comprising:

• at least one inspection area (20) suitable for housing said packaging (100);
• at least one laser source (11) with an optical axis (A) for the emission of a laser beam (12) at a wavelength substantially coinciding with a gas absorption wavelength, said at least one laser source (11) being positioned so as to direct said laser beam (12) towards said at least one inspection area (20);
• at least one detector (13) positioned so as to detect at least a portion of retro-scattered beams (12′) following the collision of said laser beam (12) emitted from said laser source (11) with a target (100,200) and provide, at the output, a representative datum of an adsorption spectrum of said gas;
• characterized in that it comprises measurement means of a distance covered by said laser beam. (12) and by said at least one portion of backscattered beams (12′) inside said packaging (100) and electronic processing means for calculating the concentration of said gas on the basis of said representative datum of said absorption spectrum and said distance covered.
