“…The IB and BB wavelengths are λ imaging =1063 nm and λ beacon =795 nm, respectively. The contents related to AO imaging is not the focus of this work and thus not presented in detail, which can be found elsewhere [17][18][19][20][21][22][23].…”

“…In this work, a method to correct the LCA between the IB and BB of ocular AO imaging systems is presented, by inserting standard trial spherical lens at the position optically conjugated with the pupil on the imaging light path. AO-FC [17][18][19], AO-CSLO [20][21][22] and AO-OCT systems developed by our group can all adopt this method. The IB and BB wavelengths in AO-OCT system are the furthest apart and the LCA is the largest among them.…”

A method to correct the longitudinal chromatic aberration (LCA) between the imaging beam (IB) and beacon beam of ocular adaptive optics (AO) imaging system is presented, by inserting trial spherical lens, i.e. chromatic aberration corrector (CAC), on the imaging light path. The LCA of the optical system, and the quantitative relation between the CAC diopter and the IB focus shift, are determined experimentally. Then the CAC diopter required for human eye imaging can be determined by using above results combined the existing ocular LCA data. The feasibility of this method was proved by imaging results of different samples with a model eye. Finally, the method was demonstrated to significantly improve the imaging effect in in vivo retinal AO optical coherence tomography imaging of volunteers. It does not require additional burdens, is easy-to-use and suitable for various ocular AO imaging systems.

We have designed, constructed and tested an adaptive optics scanning laser ophthalmoscope (AOSLO) using a bimorph mirror. The simulated AOSLO system achieves diffraction-limited criterion through all the raster scanning fields (6.4 mm pupil, 3° × 3° on pupil). The bimorph mirror-based AOSLO corrected ocular aberrations in model eyes to less than 0.1 μm RMS wavefront error with a closed-loop bandwidth of a few Hz. Facilitated with a bimorph mirror at a stroke of ±15 μm with 35 elements and an aperture of 20 mm, the new AOSLO system has a size only half that of the first-generation AOSLO system. The significant increase in stroke allows for large ocular aberrations such as defocus in the range of ±600° and astigmatism in the range of ±200°, thereby fully exploiting the AO correcting capabilities for diseased human eyes in the future.
