High-Speed High-Resolution Optical Coherence Tomography at 800 and 1060 nm

摘要

Two high speed systems for spectrometer based frequency domain optical coherence tomography are presented. A device operating at 800 nm, based on the Basler Sprint CMOS camera with linerates of up to 312,000 lps and a device based on the Goodrich SUI LHD 1024 px camera at 1060 nm with 47,000 lps are applied in a clinical environment to normal subjects. The feasibility of clinical high and ultrahigh-resolution optical coherence tomography (OCT) devices for retinal imaging at different wavelengths, capable of isotropic sampling with 70 to 600 frames per second at 512 depth scans/frame for widefield imaging and high density sampling at 1 Gvoxel are demostrated.
