SYSTEM AND METHOD FOR DETERMINING AUDIO CHARACTERISTICS FROM WITHIN A BODY |
摘要 |
A system for simultaneously detecting audio-characteristics within a body over multiple body surface locations comprising a coherent light: source directing at least one coherent light beam toward the body surface locations, an imager acquiring a plurality of defocused images, each is of reflections of the coherent light beam torn the body surface locations. Each image includes at least one speckle pattern, each corresponding to a respective coherent Sight beam and further associated with a time-fag. A processor, coupled with the imager, determines in-image displacements over time of each of a plurality of regional speckle patterns according to said acquired images. Each one of the regional speckle patterns is at least a portion of a respective speckle pattern. Each regional speckle pattern is associated with a respective different body surface location. The processor determines the audio-characteristics according to the in-image displacements over time of the regional speckle patterns. |
