| description | The invention discloses a photoelectric imaging device for wrist back side finger motion detection and an application method. The device is provided with a multi-wavelength LED array, a diaphragm structure and a photoelectric sensor. The multi-wavelength LED array is distributed around the diaphragm structure; the center of the photoelectric sensor is a photosensitive area; the diaphragm structure is a cuboid; a plurality of diaphragm taper holes are formed in the diaphragm structure, and small-end orifices of the diaphragm taper holes face the direction of the photoelectric sensor and are concentrated in a photosensitive area of the photoelectric sensor. By adopting the technical scheme, the used photoelectric sensor is in a multi-unit matrix type, and errors caused by displacement of the device can be corrected in an algorithm level; the device has the advantage of wide application, and can be used for measuring physiological parameters such as heart rate and pulse; when physiological parameters are measure |
