Abstract:
A wide field fundus camera is disclosed to implement multiple illumination beam projectors and to capture multiple retinal images at a various viewing angles to mimic wide field retinal examination with an indirect ophthalmoscope. The wide field fundus camera may incorporate a consumer image recording device with fast auto focusing so as to make the device quick to respond and easy to use. The wide field fundus camera may include narrow and broad slit beam illuminations to enhance autofocusing and imaging through less transparent crystalline lens and through haze due to Purkinje reflections from crystalline lens surfaces. Control of multiple illumination beam projectors in a programmable manner can be used to assess alignment of each illumination beam projector with the eye and to capture said multiple retinal images. Furthermore, a method is disclosed to montage said multiple retinal images into a single montage and to remove haze and reflections.
