Title:
METHOD AND APPARATUS FOR TESTING LIVING TISSUE COMPONENT, AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/170880
Kind Code:
A1
Abstract:
A method and apparatus for testing a living tissue component, and a wearable device. The method comprises: irradiating a test area with incident light with at least one preset wavelength (S310), wherein the incident light passes through the test area and then emerges from at least one emergent position to form at least one beam of emergent light, and at least two incident positions of the incident light are provided; obtaining a light intensity value corresponding to each beam of the emergent light, which light intensity value is acquired by M photosensitive surfaces, so as to obtain T output light intensities, wherein each output light intensity is obtained by processing the light intensity value of the emergent light, which light intensity value is acquired by one or more of the photosensitive surfaces, and each photosensitive surface can acquire a light intensity value of emergent light emerging from an emergent position in a preset anti-jitter range corresponding to the photosensitive surface, with 1≤T≤M (S320); and determining the concentration of at least one tissue component being tested from the at least one output light intensity corresponding to the at least one preset wavelength (S330).
