Patent

CA 2526170

The invention relates to a device for optically scanning media or objects, comprising a mirror (1) which deflects light beams (6) and is coupled to a drive unit. The inventive device is characterized in that the deflection mirror (1) can be rotated, the mirror normal (7) being tilted relative to the axis of rotation (5). An area can be scanned quickly at a large aperture such that said device is particularly suitable for use in optical remote sensing systems or remote locating systems for gases, especially hydrocarbons in the atmosphere.

L'invention concerne un dispositif de balayage optique de substances ou d'objets, comportant un miroir de déviation (1) destiné à dévier un rayonnement lumineux (6), ledit miroir étant relié à un entraînement. Ledit dispositif est caractérisé en ce que le miroir de déviation (1) est rotatif, la normale du miroir (7) étant inclinée par rapport à l'axe de rotation (5). Une surface peut ainsi être balayée rapidement avec une grande ouverture. Par conséquent, le dispositif selon l'invention est particulièrement adapté à une utilisation dans des systèmes de détection ou de localisation optiques de gaz, notamment d'hydrocarbures dans l'atmosphère.
