Spectral domain optical coherence tomography system

摘要

An optical coherence tomography device is disclosed for improved imaging. Reduced levels of speckle in the images generated by the device are obtained by forming a B-scan from a plurality of A-scans, wherein each resolution cell of the B-scan is generated through compounding of a subset of the A-scans and wherein at least some of the subset of A-scans are separated by at least half the diameter of a speckle cell both tangent to and orthogonal to the B-scan at that cell.

1. A retinal imaging device comprising:
a first imaging system having a light source emitting light at a first wavelength, said first imaging system having a first detection component conjugate to a first image plane in a first structure of the retina, a second imaging system having a light source emitting light of a second wavelength different from the first wavelength, said imaging system having a second detection component conjugate to a second image plane in a second structure of the retina wherein the first image plane and second image plane are located at different depths within the retina and wherein the first structure is in focus at the first detection component and the second structure in in focus at the second detection component; and wherein the first and second imaging systems share a common portion of an optical path.
