Abstract:
The invention provides for generating a set of signature signals that correspond to a range of depths within a target. These signature signals can include multiple individual reference signals and be can modified to compensate for specific characteristics of the target. In the preferred embodiment the members of the set of signature signals are correlated with data sets by phase rotating individual reference signals to determine maximum and minimum correlation and thereby enabling determination of the scattering characteristic of the target at each depth. Also a pilot signal is monitored to dynamically determine the phase relationship between individual reference signals and thereby avail of phase sensitive detection techniques to enhance SNR at deeper regions where multiple individual reference signals exist.

Claim (Index 5):
A multiple reference optical coherence tomography system, where said system is electrically coupled to electronics performing control and processing functions, and said comprising:\n a radiation source, generating reference radiation and probe radiation; a first beam splitter, said first beam splitter in the path of said reference radiation; an optical element, said optical element comprising:\n a first partially reflecting surface, where said first partially reflecting surface reflects at least eighty percent of said reference radiation; \n a second partially reflecting surface, where said second partially reflecting surface reflects less than ten percent of said reference radiation, and \n where said first and said second partially reflecting surfaces are in the pathway of said reference radiation and are separated by a preselected thickness of fused silica; \n a reference mirror, said reference mirror mounted on a translational device where said translational device moves co-linearly with said reference radiation, and where said translational motion is modulated by a periodic electronic drive signal, and wherein said optical thickness of said optical element and the separation between said first partially reflecting surface the reference mirror on the translational device are selected so that high order signals are centered on the turnaround points of the translational device; a first detector, wherein a pilot signal is derived from interference signals generated by interference between reference radiation reflected by said second partially reflecting surface, in combination with high order reflections between said mirror and said first partially reflecting surface, and said processor monitors said pilot signal to dynamically determine parameters of of the translational device, and identify the locations of the two turnaround points of said translational device.
