摘要： A fundus camera (10) obtains a retinal image using a light source (62), a ring aperture (58) conjugate to the cornea, and a first aperture (54) conjugate to the iris. An apertured mirror (52) redirects the ring illumination toward the eye. An objective lens (50) between the apertured mirror (52) and the eye has an entrance pupil between the iris and the cornea of the eye. The objective lens (50) directs the ring illumination into the pupil of the eye and directs a reflected image-bearing light from the retina through the apertured mirror (52). A second aperture (64), conjugate to a plane between the cornea and the iris of the eye, forms an aperture stop for the reflected image-bearing light. A third aperture (68) is conjugate to the cornea for blocking light reflected. A sensor (70) provides an image of the retina.

摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image from the tooth and a second spectral range for exciting a fluorescence image from the tooth. A polarizing beamsplitter in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor, wherein the second polarization state is orthogonal to the first polarization state. A first lens in the return path directs image-bearing light from the tooth toward the sensor, and obtains image data from the portion of the light having the second polarization state. A long-pass filter in the return path attenuates light in the second spectral range.
