Patent ID: 7847951

Claim:
An optical coherence tomography (OCT) system comprising: an OCT engine configured to provide both standard OCT imaging and spectral domain phase microscopy (SDPM) imaging, obtain image data associated with a first pass through a sample and obtain image data associated with a second pass through the sample; a processor coupled to the OCT engine and configured to process the image data associated with the first and second passes through the sample to determine a path length variation and provide an image having a resolution based on the determined path length variation; a transparent member positioned on the sample; a sample probe and a sample stage configured to provide lateral scanning of the sample through the transparent member and provide image information associated with the sample such that image information associated with a first surface of the sample can be distinguished from image information associated with a second surface of the sample; and at least one spacer positioned between the transparent member and the scanning sample, wherein a distance provided by the at least one spacer between the sample and the transparent member is used to distinguish between the image information associated with a first surface of the sample and the image information associated with a second surface of the sample.
