Abstract:
1. Apparatus for high resolution imaging of an object located at an object location and subject to movement during imaging, comprising: a) an imaging instrument employing optical coherence tomography (OCT) for scanning said object with an optical sample beam, said imaging instrument including: b) a first sensor for sensing the axial position of said object relative to said imaging instrument independently of said imaging instrument so as to detect movement of said object relative to said imaging instrument; and c) a processor for acquiring with said imaging instrument a stack of sectional en-face OCT images of said object at different axial depths within said object obtained by altering the optical path difference in said interferometer, said processor being programmed to reject any sectional images for which the movement of said object during the scanning thereof falls outside predetermined acceptable limits in response to a signal from said first sensor.
