    摘要： A passive resonant optical gyroscope comprising a cavity and operating with three frequencies comprises: a first injecting laser to inject a first optical beam into the cavity in a first direction; a second injecting laser to inject a second optical beam into the cavity in an opposite direction; a third injecting laser to inject a third optical beam into the cavity in one of the aforementioned directions, one laser amongst the injecting lasers having a master frequency, the two other injecting lasers, called the first and second slave lasers, respectively having a first slave frequency and a second slave frequency; a master servocontrol device; a first servocontrol stage comprising first and second slave devices; and a second servocontrol stage comprising first and second optical phase-locking devices respectively comprising a first and second slave oscillator to generate a first radiofrequency offset signal and a second radiofrequency offset signal.

    摘要： Tomographs comprise at least one first emission source, one first matrix detector and calculation means arranged to produce an initial tomograph of an object on the basis of radiographs arising from the first matrix detector taken from various angles. The tomography scanner comprises a second emission source and a second matrix detector arranged so that, when the object is subjected to a stress which is known at a given instant in time, the calculation means determine the changes in the object subjected to stress based only on the information from a first radiograph of the object under stress arising from the first matrix detector, from a second radiograph of the object under stress arising from the second matrix detector and the initial tomograph, the first radiograph and the second radiograph being taken at the same given instant in time.

    摘要： Method for detection of at least one reversibly photo-convertible fluorescent species (P), comprising the following steps: a) illumination of a sample comprising said or at least one of said reversibly photo-convertible fluorescent species by a periodically modulated illuminating light (FEX); and b) detection of fluorescent emission (FLU) emitted by the sample thus illuminated; characterized in that the method further comprises the following step: c) extraction of the amplitude (IFOUt) of the intensity component of said fluorescent emission exhibiting the same periodicity as said periodically modulated illuminating light and a phase quadrature with respect to the same; and in that the mean intensity of said illuminating light and the modulation frequency of the same are chosen in such a way as to maximise said amplitude of the intensity component of said fluorescent emission.
