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 (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) 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 (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.

An apparatus for multimodal imaging of an object includes a support stage for receiving an object to be imaged; an object supported on the stage, the object having been treated with a biocompatible imaging probe comprising nanoparticles carrying one or more targeting moieties and one or more diagnostic components for enabling capture of images of the object; a light source for producing a beam to illuminate the object; a filter positioned to receive and pass the beam toward the object; and a lens and camera system for capturing an image of the object. The apparatus may include a tiltable filter for filtering light from the source. The apparatus may include a mechanism for selectively directing light from the light source through a first filter assembly to produce a first beam of light of a first frequency range for illuminating an object on the stage in a first imaging mode or through a second filter assembly to produce a second beam of light of a second frequency range for illuminating an object on the stage in a second imaging mode, so that the lens and camera system captures light from the object illuminated by either the first or second beam of light to produce a first image in response to the first beam and a second image, different from the first image, in response to the second image. An x-ray source and phosphor plate may be included to provide an additional imaging mode.

A scanless display system that projects an image directly onto a retina, comprising a plurality of organic laser cavity devices. The organic laser cavity devices are placed in close proximity to a user's eye, for variably changing individual image pixels; wherein projecting the image directly onto the retina occurs by variably addressing individual image pixel locations and variably changing duration of illumination on individual image pixels upon the retina. Also included are a receiver for receiving transmitted electrical signals that include content information; a decoder for decoding received electrical signals; and a modulator for driving the scanless display under predetermined parameters.

An apparatus for imaging a tooth having a light source with a first spectral range and a second spectral range. A polarizing beamsplitter (18) 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 (68), wherein the first and second polarization states are orthogonal. A first lens (22) in the return path directs image-bearing light from the tooth, through the polarizing beamsplitter (18), toward the sensor (68), and obtains image data from the redirected portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range. Control logic enables the sensor to obtain either the reflectance image or the fluorescence image.
