The invention relates to a device (22) for observing a vehicle occupant (24) of a vehicle (20), having a lighting unit (30) for emitting infrared radiation (44) and having an image capturing unit (32), the device (22) having a hologram (46) that reflects the infrared radiation (44, 48). The hologram (46) and the lighting unit (30) are arranged relative to each other in such a way that infrared radiation (44) emitted by the lighting unit (30) is reflected on the hologram (46) and can be guided in the direction of the vehicle occupant (24). Furthermore, the hologram (46) and the image capturingunit (32) are arranged relative to each other in such a way that infrared radiation (48) radiated back by the vehicle occupant (24) is reflected on the hologram (46) and can be guided in the directionof the image capturing unit (32).

    本发明涉及一种用于对车辆(20)的车辆乘员(24)进行观察的装置(22),具有用于发出红外辐射(44)的照明单元(30)并且具有图像拍摄单元(32),其中所述装置(22)具有对红外辐射(44、48)来说反射的全息图(46)。所述全息图(46)和所述照明单元(30)如此相对于彼此来布置,使得由所述照明单元(30)发出的红外辐射(44)在所述全息图(46)上被反射并且能够朝所述车辆乘员(24)的方向引导。此外,所述全息图(46)和所述图像拍摄单元(32)如此相对于彼此来布置,使得由所述车辆乘员(24)辐射回来的红外辐射(48)在所述全息图(46)上被反射并且能够朝所述图像拍摄单元(32)的方向引导。
