Ophthalmic adaptive optics by digital holography

摘要

We are developing adaptive optics systems for aberration corrections in retinal imaging based on digital holography. Compared to existing technologies of adaptive optics, our systems do not have hardware components such as lenslet arrays or deformable mirrors. Instead, wavefxont sensing and correction are done by acquisition and numerical manipulation of optical phase by digital holography, thereby substantially reducing hardware complexity and introducing novel imaging capabilities. Experimental results are presented to demonstrate capabilities of this novel imaging system.
