“…Correspondingly, several OCT volumes with different focus position have to be recorded in order to visualize different structures that are separated in depth such as photoreceptors or nerve fiber bundles. Some approaches have been introduced to overcome the limitation of a small DOF using multiple beams [71] or an axicon lens [72]. However, these methods have been applied mainly to skin imaging and a translation of these techniques to retinal imaging is not straight forward.…”

“…TD-OCT allows for dynamic focusing, i. e. during each A-scan, the sharp focus can be shifted through the sample synchronously with the coherence gate. In FD-OCT, several images acquired at the same site with different focal planes can be compounded, allowing to focus tightly while maintaining an adequate overall depth of focus [39]. Both in time and frequency domain, one can implement optical coherence microscopy (OCM), where so-called en-face images are acquired in a plane transverse to the probing beam [40].…”

“…This enables high transverse resolution to be obtained, below 1 µm for visible light. Other elegant OCT systems have greatly increased their transverse resolution [1,[29][30][31][32], however these techniques remain more complex and often have to sacrifice their temporal resolution.…”
