<p><P>PROBLEM TO BE SOLVED: To provide a method for atraumatic measurement of human body component, and its apparatus which is categorized in the medical measuring equipment. <P>SOLUTION: In order to provide the method for atraumatic measurement of human body component, and its apparatus which is categorized in the medical measuring equipment, the component of human body is detected by measuring the propagation of laser beam in human body, modulating the laser beam, and the particular position and depth of human tissue through picking up a single-range light from scattered light are detected, by using phase-sensitive detector to process the beat signal, and picking up a single-range light from scattered light, through the use of phase-sensitive detector to process the beat signal, based on the interference between the laser beam and reference light to obtain a beat frequency, choosing a fixed optical range. This method is applied for measuring human body component atraumatically. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
