摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.

A method of making a card such as a business card or greeting card on photosensitive media using images photographically recorded in successive frames on photographic film, the photographic film including a magnetic layer. The method comprises magnetically recording at an order entry station instructions in the magnetic layer instructions specifying one of the frames, a graphic location and a source of a graphic image to be placed on the graphic location, magnetically reading the instructions from the magnetic layer, fetching the graphic image from the source specified by the recorded instructions and generating a graphic light source to project the graphic image fetched from the source, and exposing at a print station one portion of the photosensitive media to the frame on the film corresponding to the frame number specified by the recorded instructions and exposing another portion of the photosensitive media to the graphic light source.
摘要:
A selected finish is applied to a electrophotographic print of a photographic negative at a fusing station. One of a plurality of finishing rollers is moved into operative engagement with a fusing roller to provide the desired finish. The fusing roller is heated internally. The finishing rollers which are rotatable brought into contact with the fusing roller each have a different and distinct surface characteristic. Three types are surfaces are described these being a glossy surface, a matte surface and a textured surface.

A multi-field latent image bar code is photographically recorded in every half frame of a strip of photographic film, at least one of the fields of the code representing information pertaining to film type and another one of the fields representing the half-frame number.
摘要:
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.

摘要:
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, 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.
摘要:
An apparatus (10) for obtaining an image of a tooth (20) includes an image sensor and a white light source (12) providing broadband polychromatic light and an ultraviolet light source providing narrow-band light. A combiner (15) directs broadband polychromatic light and narrow band light along a common illumination path to illuminate the tooth. A polarization beamsplitter (18) directs polarized light from the illumination path along an optical axis (216). An optical coherence tomography (OCT) imaging apparatus (70) splits the low coherence light into a sample path and a reference path and a dichroic element (78) directs the polarized illumination and the sample path low coherence light along the optical axis. An image processor (100) identifies a region of interest according to either a white light image (124), a fluorescent light image (120), or both and the OCT imaging apparatus obtains an OCT image over the region of interest.
