Abstract: The invention provides an OCT system suitable for home monitoring of aspects of the retina of an eye by measuring the thickness of the retina at particular location on the retina. A preferred embodiment is capable of making measurements on both eyes and can target a desired location on the retina by means of a fixation display that is viewable by either the eye being measured or the fellow or contra-lateral eye. Various alternate embodiments are taught. In some embodiments an angular scanning device enables a small portion of the retina to be scanned and also enables flexible fixation. In some embodiments correct targeting of the location of the retina to be measured is confirmed by acquiring an image of an outer region of the retina either by means of scanning that region interspersed with acquiring A-scans at the desired location, or by acquiring a full field OCT image of the outer region of the retina while acquiring A-scans at the desired location.

Abstract: The invention provides a system and method for obtaining ophthalmic measurements whereby the inventive device is configured to be head mountable, automatically axially length aligned with a selected target, and laterally aligned so that light from an OCT source enters through the pupil of the eye under test. The frame of the head mountable OCT is customizable, capable of analyzing both the left and right eye of a subject. The inventive device can be operated by the person undergoing test. Embodiments include mechanisms for eye fixation, lateral, angular and depth scanning of target regions. A variety of embodiments are taught, including the scanning of both eyes of a subject at substantially the same time, and a configuration of a photonic module coupleable with a plurality of frames. Embodiments include a variety of OCT sources, such as MRO, swept source, time domain, and spectral domain.

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.
