Abstract: The invention provides a device (10) for acquiring images of a plant, which device comprises: i) a first structure (60) defining a cavity (33) for receiving a portion to be imaged of the plant, the cavity presenting a longitudinal axis (13) and an opening (65) at one of its ends, the cavity being defined by at least one transparent wall forming a window (12) for observing the portion to be imaged; ii) a second structure (61) extending around the window (12) and mounted to move in translation along the longitudinal axis (13) relative to the first structure, and comprising: hollow reflective optics (11, 19) extending around the window and including a reflecting surface (19) directed towards the longitudinal axis; and a plurality of image sensors (18) regularly distributed around the window (12), the field of view (77) of each sensor including at least a portion of the reflective optics so as to capture images of the portion of the plant that is surrounded by the window, which images are reflected by the refl

Abstract: A device for taking images of an article, the device including: a reflective optical system extending around an axis of symmetry, including a recess centered on the axis of symmetry and including at least one reflecting surface facing towards the axis of symmetry; and at least one imager arranged to capture at least one image of at least a portion of the article as reflected by the reflecting surface(s) substantially parallel to the axis of symmetry when the reflective optical system is arranged around the portion of the article.
