WIDE-FIELD SWEPT-SOURCE OCT AND METHOD FOR MOVING OBJECTS

Abstract: a wide-field swept-source oct method that images a moving object including an anterior chamber. including providing wavelength-tuned illumination radiation in individual illumination pulses of different centroid wavelengths, illuminating the object and imaging the object on a 2-d detector having an image recording cycle of exposure intervals and read-out intervals, emitting the pulses as a series of first pulses and second pulses, with pulses with the same centroid wavelengths repeating at least once over the illumination pulse pairs, synchronizing the pulses and the detector such that the illumination pulse pairs are grouped around every second of the read-out intervals of the sequence, and generating image pairs from the detector signals corresponding to the illumination pulse pairs, determining changes between the image data of the illumination pulses with the same centroid wavelength repeated over the illumination pulse pairs and using the changes to correct movements of the object in the image data.
