    Abstract: Scanner, method of scanning and system for scanning that allows detecting decay time characteristics of light emitted by a luminescent marking on an item which is transported, even at high speed, on a distribution/production line. The detection zone of the scanner's light sensor has a shape elongated along a path of the moving item, and the responsivity of the light sensor, within the wavelength range of the emitted luminescence light, is uniform over the detection zone. The drive current, or drive voltage, powering the excitation light source is adapted to deliver the intensity of the excitation light to the marking so that its light sensor can reliably measure the corresponding luminescence light response, and thus accurately determine a corresponding decay time value.

    Abstract: The disclosed scanner allows detecting decay time characteristics of light emitted by a luminescent marking on an item which is transported, even at high speed, on a distribution/production line. The detection zone of the scanner's light sensor has a shape elongated along a path of the moving item, and the responsivity of the light sensor, within the wavelength range of the emitted luminescence light, is uniform over the detection zone. The control unit of the scanner is further operable to adapt the drive current, or drive voltage, powering its excitation light source to accordingly adapt the intensity of the excitation light delivered to the marking so that its light sensor can reliably measure the corresponding luminescence light response, and thus accurately determine a corresponding decay time value.

    Abstract translation: 所公开的扫描器允许检测在分配/生产线上甚至高速运输的物品上的发光标记发出的光的衰变时间特性。 扫描仪的光传感器的检测区域沿着移动物体的路径具有细长的形状,并且在发射的发光的波长范围内的光传感器的响应度在检测区域上是均匀的。 扫描器的控制单元进一步可操作以使驱动电流或驱动电压适应其激发光源的功率,从而适应传递到标记的激发光的强度,使得其光传感器可以可靠地测量相应的发光光响应 ,从而精确地确定相应的衰减时间值。
