Abstract
Official abstract text for this publication.
Provided is a fluorescence imaging device comprising: a light source for irradiating a subject with a laser for exciting a fluorescent dye; a condensing lens that receives light from the light source, an endoscopic probe comprising an image fiber and a lens that is disposed on the distal end of the image fiber; a photodetector that detects return light from the subject; and an oscillating element that is connected to the image fiber or the condensing lens and that, upon application of a voltage, causes the image fiber or the condensing lens to oscillate. With this configuration, a lattice pattern of fiber elements, which appears in an image of a subject, can be cancelled in real time by oscillating the oscillating element.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical imaging device comprising: a light source for irradiating a subject with light; a condensing lens that receives light from the light source; an endoscopic probe comprising an image fiber and a lens that is disposed on the distal end side of the image fiber, the image fiber being composed of a bundle of fibers, the fibers guiding to the subject the light from the light source that is incident through the condensing lens; a photodetector that detects return light from the subject; and an oscillating element that is connected to the image fiber, the condensing lens, or the photodetector and causes the image fiber, the condensing lens, or the photodetector to oscillate wherein the oscillating element operates so as to cancel a lattice pattern of fiber elements of the image fiber in an image of a subject obtained from the photodetector. 2. The optical imaging device according to claim 1 , further comprising a display device for displaying an image of a subject produced from return light detected by the photodetector. 3. An optical imaging device comprising: a light source for irradiating a subject with light; a condensing lens that receives light from the light source; an endoscopic probe comprising an image fiber and a lens that is disposed on the distal end side of the image fiber, the image fiber being composed of a bundle of fibers, the fibers guiding to the subject the light from the light source that is incident through the condensing lens; a photodetector that detects return light from the subject; and a vibrating element that is connected to the image fiber, the condensing lens, or the photodetector and causes the image fiber, the condensing lens, or the photodetector to oscillate wherein the lens disposed on the distal end side of the image fiber is a GRIN lens coupled to the tip of the image fiber. 4. A method for processing an image of a subject by using an optical imaging device, the device comprising: a light source for irradiating a subject with light; a condensing lens that receives light from the light source; an endoscopic probe comprising an image fiber and a lens that is disposed on the distal end side of the image fiber, the image fiber being composed of a bundle of fibers, the fibers guiding to the subject the light from the light source that is incident through the condensing lens; a photodetector for detecting return light from the subject; and an oscillating element connected to the image fiber or the condensing lens, the method comprising oscillating the oscillating element in such a manner that a lattice pattern of fiber elements of the image fiber in the image of the subject is cancelled. 5. The method according to claim 4 , wherein the oscillating element is oscillated in real time during a display of the image.
