Abstract: A vehicular interior rearview mirror assembly includes a mirror head accommodating an interior mirror reflective element. The mirror reflective element has a mirror transflector that transmits near infrared light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. A camera is disposed within the mirror head and views through the mirror transflector. The camera includes an imaging sensor having a quantum efficiency (QE) of at least 15% for near infrared light having a wavelength of 940 nm. First, second and third near infrared illumination sources are disposed within the mirror head and operable to emit near infrared light that passes through the mirror transflector. The near infrared illumination sources are at respective locations at the mirror reflective element and, when powered, illuminate respective seat regions for a driver-monitoring function or an occupant-detection function.
