    • The present invention relates to a sensing device (100) for detecting a target substance (2) in an investigation region (113). The sensing device (100) comprises a sensing surface (112) with an investigation region (113) and a reference region (120) thereon. The sensing device (100) further comprises a reference element (121) located at the reference region (120). The reference element (121) is adapted to shield the reference region (120) from the target substance (2) such that light reflected at the reference region (120) under total internal reflection conditions remains unaffected by the presence or absence of the target substance (2). This allows measuring a property, typically the intensity, of light reflected at the reference region (120) independent of the presence or absence of the target substance (2). This measured property of the reflected light can be used for performing an improved correction of light reflected at the investigation region (113).
    • 本发明涉及一种用于在调查区域(113)中检测目标物质(2)的感测装置(100)。 感测装置(100)包括其上具有调查区域(113)和参考区域(120)的感测表面(112)。 感测装置(100)还包括位于参考区域(120)处的参考元件(121)。 参考元件(121)适于屏蔽参考区域(120)与目标物质(2),使得在全内反射条件下在参考区域(120)处反射的光线不会受到目标物质的存在或不存在的影响 (2)。 这允许独立于目标物质(2)的存在或不存在来测量在参考区域(120)处反射的光的特性(通常为强度)。 反射光的测量特性可用于对在调查区域(113)反射的光进行改进的校正。
