摘要： An imaging system for use with an endoscope, including a light source which emits white light and excitation light which will produce a fluorescence response by an object under inspection, an imaging camera including separate paths for processing images produced by white light and excitation light, a selection device that causes the imaging device to operate in a white light mode or an excitation light mode, and a protective device that prevents damage to high-sensitivity imaging components from exposure to excessive light input. Fluorescent image data are separated into at least red and green color bands which are separately processed to produced a video display in which normal tissue is displayed in predetermined specific color, and abnormal tissue in one or more distinctly different colors. In one embodiment, an image color interpretation guide is provided in the form of multiple color bars which are superimposed on a single video display device with the image display. of different kinds. In another embodiment, color control is provided by adjusting the amplification of the imaging components for each of the color bands while viewing tissue known to be normal using a recursive algorithm until the ratio of the maximum values of the color separation signals fall within a predetermined range. The high-sensitivity imaging components are protected by controlling impingement of light on the imagining components, selectively controlling emission of white and excitation light from the light source, and controlling the power source for the imaging components.

摘要： A low coherence beam emitted by a low coherence light source is split into two portions. One portion is transmitted from the outward end of a first single mode fiber via a detachable connector to a beam scanning probe, and then to a biological tissue; and the other is transmitted from an optical coupler placed midway along the light path via a second single mode fiber to a light path modifier. The light path modifier includes a galvanometer mirror to modify the light path length in accordance with a scan range, and a uniaxial stage to adjust the light path length to absorb the variation in lengths of different beam scanning probes. The light path is adjusted by the uniaxial stage such that the beam interference is detected for the scan range, to ensure stable acquisition of tomographic images.

摘要： In a light source unit, a switchable filter section in which an RGB filter and a fluorescence observation filter can be shifted into the light path is disposed in front of a lamp. When fluorescence image mode is selected, excitation light in a part of the wavelength band of the blue wavelength band is supplied to an electronic endoscope, and the excitation light which is reflected by the subject is shielded by an excitation light shielding filter situated in front of a CCD, whereby a fluorescence image can be obtained. On the other hand, if normal-light image mode is selected, then R, G, B light is supplied sequentially, and even under illumination of B light, the color component image in the wavelength bands which are not shielded by the excitation light shielding filter are captured, thereby yielding a normal-light image also, and hence making it possible to capture both a fluorescence image and a normal-light image by means of a single image pickup element.
