| abstract |
The present invention generally relates to optical imaging systems and methods thereof for providing images of two- and/or three-dimensional distribution of properties of chromophores in various physiological media. In particular, the present invention provides preferred embodiments of optical imaging systems, optical probes, sensor assemblies, and methods thereof for utilizing movable scanning units. A typical optical imaging system includes at least one wave source, wave detector, movable member, and actuator member. The wave source emits electromagnetic waves into a target area of the physiological medium and the wave detector generates output signal in response to electromagnetic waves detected thereby. The wave source and detector are disposed at the movable member which is moved by the actuator member so that at least one of the wave source and detector moves over different regions of the target area while generating the output signal thereby. Accordingly, the optical imaging system and optical probes of the present invention can scan the target area which is substantially larger than the scanning area of its scanning unit. |
