Abstract
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.
Claims6
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.
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.
