Abstract

TITRE : Dispositif pour observer un passager de véhicule Dispositif (22) pour observer un passager (24) d’un véhicule (20) comprenant une unité d’éclairage (30) pour émettre des rayons infrarouges (44) et une unité de prise de vue (32) et un hologramme (46) réfléchissant les rayons infrarouges (44, 48). L’hologramme (46) et l’unité d’éclairage (30) sont disposés l’un par rapport à l’autre pour que les rayons infrarouges (44) émis par l’unité d’éclairage (30) soient réfléchis par l’hologramme (46) dirigés vers le passager (24). L’’unité de prise de vue (34) est disposée pour que les rayons infrarouges (48) renvoyés par le passager (24) soient dirigés vers l’unité de prise de vue (32). Figure 4TITLE: Device for observing a vehicle passenger Device (22) for observing a passenger (24) of a vehicle (20) comprising a lighting unit (30) for emitting infrared rays (44) and a photo-taking unit view (32) and a hologram (46) reflecting the infrared rays (44, 48). The hologram (46) and the lighting unit (30) are arranged relative to each other so that infrared rays (44) emitted by the lighting unit (30) are reflected by the hologram (46) directed towards the passenger (24). The camera unit (34) is arranged so that the infrared rays (48) reflected by the passenger (24) are directed towards the camera unit (32). Figure 4
