Abstract
- To achieve 3D high-cellular resolution, a great effort, in the past years, was made to develop Adaptive Optics (AO)-OCT systems. However, such systems require quite complex, expensive and cumbersome hardware, making clinical transfer challenging. Recently, we demonstrated that the use of spatially incoherent illumination in Time-Domain Full-Field (FF)-OCT offers a valuable advantage: the lateral resolution is almost insensitive to ocular aberrations that only affect the FF-OCT signal level. We took advantage of this property to image in-vivo photoreceptor mosaic without using an AO technique. Nevertheless, the FF-OCT technique was still facing some challenges in providing consistent and reproducible images, mainly due to axial eye motion and reduced signal level. Here, we present the Adaptive Glasses-assisted FF-OCT, where an adaptive lens is placed just in front of the eye, like spectacles, enabling correction of the first 10 Zernike polynomials, increasing the FF-OCT signal level.
