摘要	A device for measuring the progress of healing of a wound over time includes at least one diode laser source that provides respective input wavelengths into at least one source fiber, a first optical switch that sequentially switches wavelengths among the respective input wavelengths into the at least one source fiber, a probe that does not touch the wound dunng use, the probe including the at least one source fiber and at least two detectors spaced thereon, an optical system that provides source light from the at least one source fiber to the wound and that detects light scattered by the wound surface and provides the scattered light to the detectors, and a processing unit responsive to outputs of the detectors for providing at least four independent measurements for calculation of an absorption coefficient /Ia and a scattering coefficient /I's of the light by the wound
其他摘要	用于测量伤口随时间愈合的进展的装置包括至少一个二极管激光源，其将相应的输入波长提供到至少一个源光纤中，第一光开关将各个输入波长中的波长顺序地切换到至少一个中。源光纤，不接触伤口使用的探针，包括至少一个源光纤和至少两个间隔开的探测器的探针，提供从至少一个源光纤到伤口的光源的光学系统检测由伤口表面散射的光并将散射光提供给检测器，以及响应于检测器的输出的处理单元，用于提供至少四个独立的测量，用于计算光的吸收系数/ Ia和散射系数/ I'伤口
主权项	A device for measuring the progress of healing of a wound over time, comprising: at least one diode laser source that provides respective input wavelengths into at least one source fiber; a first optical switch that sequentially switches wavelengths among the respective input wavelengths into said at least one source fiber; a probe that does not touch the wound during use, said probe including said at least one source fiber and at least two detectors spaced thereon; an optical system that provides source light from said at least one source fiber to the wound and that detects light scattered by the wound surface and provides the scattered light to said at least two detectors; and a processing unit responsive to outputs of said at least two detectors for providing at least four independent measurements for calculation of an absorption coefficient μα and a scattering coefficient μ's, whereby the progress of the healing of the wound over time may be determined from said absorption coefficient Pa and the scattering coefficient fia .
