The invention concerns a detection system () for measuring at least one characteristic of an inked zone () comprising at least one sensor adapted to sense a light radiation reflected by said inked zone () and to generate a measurement signal representing at least the characteristic of the inked zone (). Such a system further comprises at least one first optic fiber (), adapted to convey up to the neighborhood of the inked zone (), a light radiation emitted by a light source ().

System for detecting offset printing using same

A spectrometry device comprising at least one wavefront-dividing interferometer comprising at least two unbalanced arms and at least one air wedge, a device for imaging interference fringes, an imaging sensor of the fringes and a processor that processes a signal derived from the sensor.

Coherence spectrometry devices

A system for detecting a chemical element within a material including at least one laser emission means for ionizing part of the material to generate fluorescence; at least one transmitting Bragg grating that filters the wavelength corresponding to the deexcitation wavelength of the element; and at least one photodiode that detects a line corresponding to the filtering wavelength, wherein the at least one Bragg grating is mobile to vary the filtering wavelength.
