Abstract: A device for detection of surface defects on a terminal surface of an optical fiber. The device includes a digital microscope configured to capture an image of a terminal surface; and a mechanism for analyzing the image configured to detect surface defects present on the terminal surface, the analysis mechanism integrating a “U-Net”-type neural network having had its training phase carried out via an enhancer. The enhancer is configured to create training images, intended to train the neural network, based on reference images. The training images are obtained from the reference images by only applying flips, rotations and/or luminosity, contrast, or shade variations to the reference images.

Abstract: Device for inspecting by interferometry the geometry of an end face of a ferrule of a multi-fiber optic connector. The device allows the ferrule to be held by a holder of the ferrule, and a supporting plate including a receiving device adopts a position in space that is mainly conditioned by the interaction of the receiving device of the supporting plate with an engagement device provided on the ferrule. The supporting plate includes a reference surface with respect to which is measured by interferometry the geometry of the end face of the ferrule, the position of this reference surface being preset with respect to the orientations of the receiving device.

Abstract: A device and method for monitoring a high-pressure pump in a turbomachine fuel supply circuit by detecting opening of a pressurizing and shut-off valve mounted on an outlet side of a fuel flow regulating valve, by measuring rotational speed of the turbomachine corresponding to the opening of the pressurizing and cut-off valve, and by monitoring change in a value of the rotational speed to propose replacement of the high-pressure pump when the measure value rotational speed reaches a predetermined threshold.
