Schematic layout of the long range SS-OCT system. SS: swept source; MO1,2,3,4: microscope objectives; AOD11, 12, 21, 22: acousto – optic deflectors; POLC: polarization controllers; GS: galvanometer scanner equipped with a mirror to scan along X direction; Tx: scanner controller; L1, L2: lenses; M: mirror; DFS1,2: digital frequency synthesizer; DCR: dispersion compensator rod; AL: achromatic lens; OL: Objective lens; BS: beam-splitter; PC: personal computer equipped with a NI-5124 digitizer to decode each axial scan and produce the image on the PC display.

B-scan images of a tilted mouse head obtained with a long-range constant sensitivity SS-OCT system. a: Conventional B-scan carried by C1; b: Conventional B-scan carried by C2; c): A long range B-scan produced by the long range imaging software; d: experimentally measured sensitivity curve in air representing the system sensitivity variation as a function of reference OPD. The curve is positioned so that OPD in the graph corresponds to the OPD in a, b and c; e a photo of the sample. The distance z in the object is OPD/2. Due to a long exposure time the scanning beam is visible as a white line across the eye and surrounding tissues.
