<p>An imaging system (2) wherein an optical signal (185, 195) is transmitted to both a sample (25) to be measured and a rotating element (175) which is calibrated to the system. A return signal (186, 196) is detected by the system, and a scan analyzer and correction unit (160) uses the system calibration information along with synchronization information (177, 171) to correct for return signal degradation or errors due to imperfections in the rotating element (175) in real time. This allows for an accurate measurement of the sample (25). The system (2) can also include a coarse path-length adjustment unit (45) to allow the system to track a region of interest within a sample (25) to further allow for accurate sample measurement.</p> |
