Abstract: A line-field Fourier-domain optical coherence tomography, OCT, imaging system, comprising: a curved mirror, and a scanning element at a first focus of the mirror which scans, via the mirror, a line of light across an object at a second focus of the mirror, and receives, via the mirror, light scattered by the object and aberrated by the mirror to form an aberrated line of light; a photodetector array; an interferometer which projects an interference line of light resulting from an interference between a reference light and the aberrated line of light onto the photodetector array. The OCT imaging system generates OCT data based on the interference line of light detected by the photodetector array, and corrects the OCT data using phase information in the OCT data such that the corrected OCT data has less optical aberration than the OCT data.

Abstract: A binocular OCT imaging system for simultaneously imaging regions of a first eye and second eye using an interferometer having a reference arm first sample arm and second sample arm, by: obtaining an electrical signal (S) having first frequency components spanning a first band and caused by interference between reference light in the reference arm with light reflected from the first eye in the first sample arm, and second frequency components spanning a second band and caused by interference between the reference light and light reflected from the second eye in the second sample arm; and generating OCT images of: the region of the first eye using first frequency components in a portion of the first band not overlapping the second band; and the region of the second eye using second frequency components in a portion of the second band not overlapping the first band.
