Summary:An imaging system (200) for imaging and generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positionedso that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the radiation splits out in different directions into at least a non-dispersed part (40) and a dispersed part (50), and those are imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed part, the imaged non-dispersed part, and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums. 用于进行对象(10)的成像并生成该对象(10)的真实性度量的成像系统(200)包括色散成像配置(30)和图像传感器配置(60)。定位色散成像配置(30)和图像传感器配置(60)，使得在来自对象(10)的电磁辐射(20)照射色散成像配置(30)的情况下，该辐射在不同方向上至少分成非色散部分(40)和色散部分(50)，并且利用图像传感器配置(60)对非色散部分(
