Abstract
A vehicular cabin monitoring system includes an interior rearview mirror assembly having a mirror head that accommodates a prismatic mirror reflective element and a camera. The prismatic mirror reflective element is adhesively attached at a mirror back plate of the mirror head. A not-optically-clear adhesive (NOCA) layer is disposed between a mirror reflector coating at a rear side of the prismatic mirror reflective element and the mirror back plate. The camera views through (i) the NOCA layer, (ii) the mirror reflector coating and (iii) the glass substrate of the prismatic mirror reflective element. Electronic circuitry of an electronic control unit (ECU) includes an image processor for processing image data captured by the camera. With the mirror assembly mounted at an interior portion of a vehicle, image data captured by the camera is processed at the ECU for an occupant monitoring function or a driver monitoring function.
