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.
