The optical design for a contact type portable eye imaging apparatus, including the imaging optics and illumination optics are proposed, which utilizes miniature image sensor and solid state light emitting technology, as the next generation of medical imaging devices, in particular in ophthalmic ima

대표청구항 ▼

1. An eye imaging optical apparatus, comprising: a transparent optical window with a frontal surface fit with the profile of the cornea of the eye and coated with a layer of optical reflection reduction coating;a transparent optical lens with conical shape located behind the optical window and separated with a small gap, with its conical surface coated with a thin optically absorptive layer, and with its frontal surface made with profile as same or similar to the profile of the back surface of the optical window;a first relay optical lens, which comprises one or multiple lenses, to form a real image of the internal eye structures, or fundus near its back focal plane;a second relay optical lens, which comprises one or multiple lenses, with its front focal plane located next to the back focal plane of the first relay lens to form the image of the internal structure, or fundus at the infinity;a miniature optical lens, which comprises multiple optical lenses, with its optical aperture located near the back focal plane of the second relay lens and along the optical axis formed by the optical lenses before it; anda miniature electronic area or image sensor, located at the back focal plane of the miniature optical lens in the front of it, to capture the images of the internal structure of the eye or fundus;wherein a real image of the optical aperture of the miniature optical lens is formed near the anterior surface of the crystalline lens of the eye or the iris plane when the eye imaging apparatus is used to photograph the posterior segment of an eye. 2. The eye imaging optical apparatus recited in claim 1 where the gap between the optical window and optical lens behind it is filled with air or optical clear index matching materials. 3. The eye imaging optical apparatus recited in claim 1 wherein the focus of the imaged objects is adjusted by the effectively and internally moving the position of the miniature lens relative to the image sensor. 4. The eye imaging optical apparatus recited in claim 1 wherein the magnification of the images is changed by the effective change of the optical focal length of the miniature lens in the front of the image sensor. 5. The eye imaging optical apparatus recited in claim 1 wherein said eye imaging optical apparatus is used to image the posterior and anterior of an eye. 6. The eye imaging optical apparatus recited in claim 1 wherein the optical window is in direct contact with the cornea of the eye or separated from the cornea with a thin layer of optically clear gel when the imaging apparatus is used to photograph the posterior of an eye. 7. The eye imaging optical apparatus recited in claim 1 wherein the eye structure or fundus is illuminated by the light emitted from a light source which then passes through a light conditioning device located behind the optical window, and outside and around the conical shaped lens. 8. The eye imaging optical apparatus recited in claim 1 wherein said eye imaging optical apparatus generates 3D stereoscopic images when two miniature cameras are used, and located effectively at the back focal plane of the miniature optical lens, and with their optical axes in parallel and separated by a small distance. 9. The eye imaging optical apparatus recited in claim 1 wherein said eye imaging optical apparatus generates 3D stereoscopic images when two miniature optical lenses are used together with two cameras located at the back focal plane of the miniature optical lenses, and with the optical axes of lens/camera module in parallel and separated by a small distance. 10. An eye imaging apparatus comprising: a housing;a light source disposed inside the housing and configured to illuminate an eye;an optical imaging system comprising: an optical window with a radius of curvature closely matching a curvature of a cornea of the eye at a front end of the housing,an imaging lens optically aligned with the optical window, the imaging lens positioned immediately behind and separated from the optical window by agap filled with air,at least first and second relay lenses, andat least one miniature lens configured to form an image of the eye based on light received from the at least first and second relay lenses; anda miniature image sensor configured to receive the image of the eye formed by the at least one miniature lens;wherein a real image of an optical aperture in the at least one miniature lens is formed near an anterior surface of a crystalline lens of the eye when the eye imaging apparatus is being used to photograph a posterior segment of the eye.
