摘要：
An apparatus for separating an image of a target into a directly scattered component and a multiply scattered component by providing a stationary field stop having a first region and associated detector confocal to a point on the target. During a first interval, a light source directs a first beam to the target and the directly scattered component is selected by the first region. During a second interval, the light source directs a second beam to the target and the multiply scattered component us selected by the first region and its associated detector. Alternatively, a light source directs a first beam to the target and the directly scattered component is selected by the first region of the field stop and its associated detector, while the second region and its associated detector select for multiply scattered light.
