摘要： Methods for optical imaging, particularly with optical coherence tomography, using a low coherence light beam reflected from a sample surface and compared to a reference light beam, wherein real time dynamic optical feedback is used to detect the surface position of a tissue sample with respect to a reference point and the necessary delay scan range. The delay is provided by a tilting/rotating mirror actuated by a voltage adjustable galvanometer. An imaging probe apparatus for implementing the method is provided. The probe initially scans along one line until it finds the tissue surface, identifiable as a sharp transition from no signal to a stronger signal. The next time the probe scans the next line it adjusts the waveform depending on the previous scan. An algorithm is disclosed for determining the optimal scan range.

摘要： Arrangements and methods are provided for obtaining data associated with a sample. For example, at least one first electro-magnetic radiation can be provided to a sample and at least one second electro-magnetic radiation can be provided to a reference (e.g., a non-reflective reference). A frequency of such radiation(s) can repetitively vary over time with a first characteristic period. In addition, a polarization state of the first electro-magnetic radiation, the second electro-magnetic radiation, a third electro-magnetic radiation (associated with the first radiation) or a fourth electro-magnetic radiation (associated with the second radiation) can repetitively vary over time with a second characteristic period which is shorter than the first period. The data for imaging at least one portion of the sample can be provided as a function of the polarization state. In addition or alternatively, the third and fourth electro-magnetic radiations can be combined so as to determine an axial reflectance profile of at least one portion of the sample.
