    Abstract: In accordance with the present invention, embodiments of interferometers are presented that improves both the polarization dependency problem and helps prevents light from being reflected back into the light source, among other things. Interferometer embodiments can include an isolator coupled to a light source and polarization dependent optics coupled with the isolator to provide light to a reference arm and a sample arm, wherein reflected light provided to optical detectors is such that a polarization independent optical signal can be formed in an optical signal processor coupled to the optical detectors, and the isolator blocks reflected light from the reference arm and the sample arm from entering the light source. In some embodiments, a balanced detection system can be utilized to reduce noise.

    Abstract: Optical coherence tomography ("OCT") corneal mapping apparatus includes an OCT apparatus having a rotating helical mirror for altering a reference beam path in the OCT apparatus; a raster scanner for raster scanning sampling optical output from the OCT apparatus; a curved mirror for transferring the sampling optical output from the raster scanner to an eye and for transferring sampling optical output reflected from the eye back to the OCT apparatus through the raster scanner; and an analyzer, coupled to the raster scanner, the rotating helical mirror, and reference and sampling interaction output from the OCT apparatus. The analyzer causes the raster scanner to scan the sampling optical output to points in a raster; causes the rotating mirror to alter the length of the reference beam path over a predetermined amount at each of the points in the raster; and provides the corneal mapping from the reference and sampling interaction output at the points in the raster.

    Abstract: A Fourier-domain optical coherence tomography (OCT) imager is presented. An OCT imager according to the present invention can have an auto-alignment process. The auto-alignment process automatically adjusts at least one optical component of a spectrometer of the imager so that the spectrometer is aligned during an imaging session. In addition to the auto-alignment process, OCT spectra are normalized for background spectra and for noise characteristics in order to provide a more accurate and clear OCT image.
