    • An interior mirror which enables surveillance of a vehicle driver even at night, in tunnels and the like, without obstructing a forward field of vision of the vehicle driver or subjecting the vehicle driver to psychological pressure due to the presence of a surveillance device. Light with wavelengths in the infra-red light region is illuminated from infra-red LEDs inside a housing. When this light enters a filter from a rear face side thereof, the infra-red light that has wavelengths outside a range X is reflected, and the infra-red light that has wavelengths inside the range X is transmitted. This transmitted infra-red light is irradiated at the vehicle driver. This infra-red light is reflected from the vehicle driver, is incident at the filter from the front face side thereof and is again transmitted to the rear face side, and enters a lens of an infra-red camera.
    • 一种内部镜子,即使在夜间,隧道等中也能够监视车辆驾驶员,而不会妨碍车辆驾驶员的前方视野或者由于监视装置的存在而使车辆驾驶员受到心理压力。 在红外线区域内的波长的光由外壳内的红外线LED照亮。 当该光从其背面侧进入滤光器时,反射具有范围X以外的波长的红外光,并且发射具有范围X内的波长的红外光。 在车辆驾驶员处照射该红外光。 该红外光从车辆驾驶员反射,从其正面侧入射到过滤器,并再次传递到后面侧,并进入红外相机的透镜。
