【摘要】双波长视网膜成像自适应光学系统非常适用于视网膜微血管的高对比度和高分辨率成像。本文重点研究了双波长自适应系统的轴向色差补偿问题。首先对轴向色差进行了测量，对实测波前进行了分析，并给出任意波前轴向色差补偿法。自适应校正实验结果显示，色差补偿后，波前均方根误差减小到0.16λ（λ=589 nm），视网膜微血管分辨率提高到6μm。这项工作可用于视网膜成像的临床应用。更多还原

【Abstract】 Dual-wavelength retinal imaging adaptive optics systems are suitable for high contrast and resolution imaging of retinal capillaries. The compensation of the Longitudinal Chromatic Aberrations(LCAs) in dual-wavelength adaptive systems is researched. The LCA is measured, the measured wavefronts are analyzed, and the arbitrary wavefront LCA compensation method is given. An adaptive correction experiment is carried out and the experimental results indicate that the root mean square error of the wavefront is reduced to0.16 λ(λ=589 nm) and the retinal capillary resolution is improved to 6 μm. This work may be used for the clinical applications of retinal imaging.更多还原
