Abstract: In a thermally regulated climate chamber for testing equipment, a thermoelectric unit is arranged through the wall of the climate chamber, each thermoelectric unit having two faces, an internal face inside the climate chamber and an external face outside the climate chamber, wherein a heat exchange end for an external face of a thermoelectric unit of a secondary thermal regulation circuit is placed in thermal contact with each external face of thermoelectric unit, the secondary thermal regulation circuit being external to the climate chamber and including a heat-transfer fluid circuit, a cold source, a hot source, a mixing device, a circulation pump and sensors. A chamber temperature regulation system controls the electric current of the thermoelectric unit and to control at least the mixing device and the circulation pump of the secondary thermal regulation circuit as a function of a chamber temperature setpoint and of sensor measurements.

Abstract: Disclosed is a method for reducing the Kerr effect in an interferometry measuring device including a generator configured to emit an input periodic light signal, and a Sagnac interferometer in which two counterpropagating signals travel and combine so as to form a periodic output signal having at least two power values, the method including: determining a phase shift between the two counterpropagating signals a first time, and cancelling out the phase shift; and then determining a phase shift between the two counterpropagating signals a second time; and adjusting the ratio between the average powers of the counterpropagating signals so as to cancel out the value of the phase shift determined in the second determination. Also disclosed is an interferometry measuring device configured to implement such method.

Abstract: This relates to a dosimeter including a light source capable of generating a light beam, an optical coupler-splitter, a radio-sensitive optical fiber, a first photodetector arranged to record a power measurement of the light beam transmitted through the radio-sensitive optical fiber, a reference optical arm, a second photodetector arranged to record a reference power measurement of the light beam transmitted through the reference optical arm, and an electronic system configured to extract a differential radiation induced attenuation measurement in the radio-sensitive optical fiber with respect to the reference optical arm. The light beam is non-polarized or depolarized, or, respectively, the light beam is polarized and the radio-sensitive optical fiber is a polarization-maintaining fiber.
