Paper Abstract
We describe a method we call "stripe field imaging" that is capable of capturing wide field color fundus videos and
images of the human eye at pupil sizes of 2mm. This means that it can be used with a non-dilated pupil even with bright
ambient light. We realized a mobile demonstrator to prove the method and we could acquire color fundus videos of
subjects successfully. We designed the demonstrator as a low-cost device consisting of mass market components to show
that there is no major additional technical outlay to realize the improvements we propose. The technical core idea of our
method is breaking the rotational symmetry in the optical design that is given in many conventional fundus cameras. By
this measure we could extend the possible field of view (FOV) at a pupil size of 2mm from a circular field with 20° in
diameter to a square field with 68° by 18° in size. We acquired a fundus video while the subject was slightly touching
and releasing the lid. The resulting video showed changes at vessels in the region of the papilla and a change of the
paleness of the papilla.
