    Abstract: A physiological detection device includes system including a first array PPG detector, a second array PPG detector, a display and a processing unit. The first array PPG detector is configured to generate a plurality of first PPG signals. The second array PPG detector is configured to generate a plurality of second PPG signals. The display is configured to show a detected result of the physiological detection system. The processing unit is configured to convert the plurality of first PPG signals and the plurality of second PPG signals to a first 3D energy distribution and a second 3D energy distribution, respectively, and control the display to show an alert message.

    Abstract: A microcirculation detection system including a heating device, a photosensitive array and a processing unit is provided. The heating device is used to heat a skin area. The photosensitive array is used to detect outgoing light from the skin area, and output a plurality of brightness variation signals respectively at different time points within a heating period. The processing unit is used to calculate a change of an array energy distribution varied within the heating period according to the plurality of brightness variation signals to accordingly identify a microcirculation state.
