| Zusammenfassung: | A heart rate detection system includes a light source outputting a light beam, an acousto-optical sensing element having a crystalline material, and a light analysis module. The crystalline material has an input end, an output end and a sensing end. The input end is connected to the light source. The light beam emits into the input end, passes through the crystalline material, and emits out of the output end. An acoustic wave signal is received by the sensing end and changes a structure of the crystalline material. The light analysis module is connected to the output end and receives and analyzes the light beam that passes through the crystalline material. |
