A flood-illuminated adaptive optics ophthalmoscope for retinal multilayer imaging is introduced in this paper. By arranging an alterable stop in the illumination path the illuminated area of retinal layer can be changed. A laser beacon for wavefront sensing is formed when the stop is a narrow aperture. The large aperture allows flood illumination and expands imaging field. A moveable imaging camera can focus on different layers of the retina. In the confirming experiment a subject who was a 25-years-old normal health Chinese male was imaged. We got clear images of photoreceptor layer blood vessels and nerve fiber layer. 2011 IEEE.

Comparing with the writing method of plane pattern spherical pattern' has some remarkable different on several points. Firstly it is difficult to spin-coated a uniform photoresist film on a spherical substrate especially the ratio of spherical radius to caliber is smaller and the spin-coated way must match the ratio of spherical radius to caliber. Secondly if the sphere couldn't be regarded as a plane a so-called concentric optical scan movement way must be applied for the generation of spherical pattern because the reflex of substrate will affect the quantity of illumination. Commonly an alignment technique is indispensable with pattern generation of spherical surface by the concentric optical scan in order to ensure the orthogonal intersection of focusing laser beam and writing surface. Thirdly a uniform velocity control must be considered for the laser direct writing method on a spherical substrate. Otherwise the exposure time of photoresist will be different and the line widths of pattern will be also different at different areas. Fourthly commonly because the errors of concentric machine and substrate surface shape are bigger so focusing servo-control technique is also needful for writing a pattern on a spherical substrate. Focusing servo-control may keep the focal spot on the spherical surface by a focus detection and control system in the course of writing pattern. Using these techniques we fabricated a line width of 7m and a period of 600m isometric mesh on the concave of a spherical substrate.
