Abstract:
The present invention discloses a PPG imaging device and a PPG measuring method. The PPG imaging device comprises a light emitting unit, a collimator unit, a beam splitter unit, an image sensing unit, and an image analysis unit. The light emitting unit provides an incident light signal. The collimator unit receives the incident light signal and transforms the incident light signal into a parallel light signal. The beam splitter unit receives the parallel light signal and reflects it to a tested region. The image sensing unit receives a reflected light signal reflected from the tested region and converts it into image signals. The image analysis unit connects with the image sensing unit and analyzes the image signals to obtain PPG signals of the tested region. The PPG imaging device may be arranged in an anti-light pollution unit, whereby to prevent from optical interference and obtain higher measurement precision.
