A band-pass IR light photodetector for wearable intelligent glasses in a drowsiness-fatigue-detection system

This paper proposes a band-pass infrared (IR) light photodetector, which is applied to our developed wearable intelligent glasses in a drowsiness-fatigue-detection (DFD) system. The proposed band-pass IR photodetector is designed to detect IR light in the wavelength range from about 810 to 890nm. The benefits of the proposed band-pass infrared photodetector are to provide higher SNR, decrease the ambient environmental light image to a minimum, and effectively enhance detection accuracy. As a result, the recognition algorithm is easier to be implemented and mounted on the light-weight version wearable intelligent glasses with high detection accurate rate.
