Embodiment 1
[0105] The optical sampling bracelet is not encrypted, that is, the position distribution of the optical fiber port on the inner side of the bracelet is exactly the same as the position distribution of the photosensitive unit in the photosensitive array, as shown in Figure 6-2 As shown; the light-emitting circuit emits white light and a certain amount of infrared light at the same time; the photosensitive array adopts CCD photosensitive element; the signal processing module adopts a micro DSP module; the wireless communication module chooses a Bluetooth module; the smart terminal chooses a smartphone; Closed ring shape; there is a layer of transparent glass on the inner side of the light sampling bracelet to prevent direct contact between the fiber port and the skin.
[0106] The sampling frequency of the light sampling bracelet is set to 100Hz, that is, the light sampling bracelet sends 100 frames of light data distribution corresponding to the reflected light of the wrist sk...
Embodiment 2
[0126] The light sampling bracelet adopts physical encryption, that is, the relative coordinate positions of the two ports of the same optical fiber in the photosensitive array correspond randomly to the relative coordinate positions on the inner side of the light sampling bracelet (such as Figure 6-1 shown); the light-emitting circuit emits white light and a certain amount of infrared light at the same time; the photosensitive array adopts CCD photosensitive element; the signal processing module adopts a micro DSP module; the wireless communication module chooses a Bluetooth module; the smart terminal chooses a smart phone; light sampling bracelet It is in the shape of a closed ring; there is a layer of transparent glass on the inner side of the light sampling bracelet to prevent direct contact between the fiber port and the skin.
[0127] The sampling frequency of the light-sampling bracelet is set to 100Hz, that is, the light-sampling bracelet sends 100 frames of light-refle...
