Abstract : We present an ultrahigh resolution spectral-domain optical coherence tomography imaging system using a broadband superluminescent diode light source emitting at a center wavelength of 1.3µm. The light source consists of two spectrally shifted superluminescent diodes that are coupled together into a single mode fiber. The effective emission power spectrum has a full width at half maximum of 200nm and the source output power is 10 mW. The imaging system has an axial resolution of 3.9µm in air (~3.0µm in biological tissue), and a lateral resolution of 6.5µm.Thesensitivity and the maximum line rate are 95 dB and 46 kHz, respectively. Images of an infrared viewing card and a cornea from human eye suffering from glaucoma showing Schlemm’s canal are presented to illustrate the performance of the system.
