Abstract
To solving the slow and complex scanning of spot-scan model in optical coherence tomography (OCT), a fast lateral line-scan model was investigated with doublet-cylinder-lens(DCL). For the DCL, the elimination of spherical aberration was theoretically studied, as well as the beam model and the focus. The parameters and signal characteristics of the confocus microscopy system (CFMS) with DCL were simulated and brought forward. The relation between the transverse resolution and the numerical aperture and the depth of focus (DOF) was discussed in the OCT. Results show that the spherical aberration and the sine aberration of the DCL with K9-ZF2 glass are effectively eliminated. Because the beam is uniformly focused on the arc-sagitta-plane of cylinder lens and produces the parallel interference pattern or fringe with axial symmetry, the transverse resolution interacted by the numerical aperture and the DOF is improved. The scanning velocity of the CFMS with DCL is faster three orders of magnitude than the traditional spot-scan model. The transverse resolution with system aperture 50.8 mm is 15 m. This advanced system will be valuable in real-time vivo imaging.
