    摘要: The present disclosure concerns a broadband hyperspectral imaging spectrophotometer configured to analyze an object and includes an illumination assembly having a source for emitting a light beam and configured so that the light beam scans line by line the object to be analyzed, a focusing mirror, a first mirror folding, and a planar scanning mirror movable in rotation. The illumination assembly, the focusing mirror, the first folding mirror and the planar mirror are arranged to bring the light beam to the object along a line which will be displaced on the object via the scanning mirror. The imaging spectrophotometer further includes two measuring sensors by a distance between the object and the scanning mirror. The focusing mirror is movable in translation to adapt the imager to the measured distance by the measuring sensors.
