摘要： An compact imaging apparatus having an OCT function is provided. An image formed of the illuminating-light reflected from a examination area is displayed on a monitor. A signal-light for obtaining an optical tomographic image is guided in a fiber through an insertion portion and projected onto a living tissue measurement area by an illuminating lens. The measurement area is scanned with the signal-light by a Piezo actuator moving the output face of the fiber. An OCT obtaining-portion obtains and displays on a monitor an optical tomographic image by using the interference caused by the signal-light reflected from the measurement area and a reference-light. By performing the scanning with the signal-light using an image-obtaining lens, the need to insert a probe for obtaining an optical tomographic image through a forceps port is eliminated. Therefore, the number of required forceps ports is reduced, and the insertion portion can be made thin.

摘要： A light source device for use in an image capturing device such as an endoscope capable of reducing size and cost, and preventing heat generation at an illuminated position. An illumination unit of the endoscope includes LED light sources for emitting ultraviolet light, fluorescent fibers for generating red, green and blue light respectively by irradiation of the ultraviolet light, a sampling light source, and an excitation light source. Upon capturing a normal image, the ultraviolet light is emitted sequentially from the LED light sources to cause the fluorescent fibers to generate the red, green and blue light. The light of each color is passed through a light guide and irradiated on an observation area of a living body. Thereafter, reflected images attributable to the light of each color are captured with a CCD image capturing element of a charge multiplying type, and captured images are displayed on a monitor.

摘要： Low coherence light emitted from a light source is separated by a fiber coupler into a signal light, which is to be projected onto a target subject, and a reference light, which is to be modulated by a piezoelectric element. The signal light reflected from a predetermined depth of the target subject is synthesized with the reference light. The intensity of the interference light obtained thereby is detected by a balance differential detector, subjected to signal process by a signal processor, and displayed as a tomographic image on a display. The spectral width of the pulse light emitted from a pulse light source formed of an Er doped fiber is expanded in a zero dispersion fiber having a negative dispersion property, whereby the coherence length is shortened. The conventionally employed KTM Ti sapphire laser becomes unnecessary, and the light source becomes compact and inexpensive.

摘要： A fiber coupler separates, the low-coherence light emitted from a light source into a signal-light to be projected onto a target subject and a reference-light whose wavelength is shifted by a Piezo element, and combines the signal-light reflected from a predetermined depth within the target subject with the reference-light. A balance differential detector detects the signal strength of the interference-light after said combining, and said signal is processed by the signal processor; whereby an optical tomographic image of the target subject is obtained, and output to a monitor and to the diagnostic data output portion. The diagnostic data output portion performs pattern-matching between the optical tomographic image of the target subject and the pattern of a prerecorded standard optical tomographic image obtained of a normal tissue. If the two patterns substantially match, that the target subject is in the normal state is output to the monitor and displayed.

摘要： A temperature distribution which is of the sum of the temperature distribution generated by a laser beam emitted from above and the temperature distribution generated by the laser beam emitted from below at the same irradiation position in a film which is of a subject of laser annealing is caused to be substantially constant in a thickness direction of the subject to be annealed. Therefore, a solid-liquid interface is formed substantially perpendicular to a surface direction of the subject to be annealed, crystal growth in a lateral direction is promoted, and a large crystal grain can be formed. As a result, even if the subject to be annealed has a thin film thickness, the annealing process can be performed by utilizing input energy without waste of the input energy.

摘要： A laser beam emitted from a laser light source is transmitted plural times through an a-Si layer on a substrate to be annealed by irradiating the a-Si layer with the laser beam so that a direction of the laser beam is reversed along an optical path along which the laser beam is transmitted through the a-Si layer. Since an operation in which energy is absorbed is repeated plural times when the laser beam is transmitted through the a-Si layer, input energy of the laser beam can be utilized without waste. Further, in an area of the a-Si layer that the laser beam is transmitted plural times, crystal growth in a lateral direction can be realized to form a large crystal grain in such a manner that an energy absorption distribution generated in a transmission direction is made constant to cause a solid-liquid interface to be flat along the optical path.

摘要： An apparatus for obtaining a cellular image to be used in performing a test for pathology of the sentinel lymph node, which is the first lymph node a cancer metastasizes to. The gamma radiation emitted from a near-infrared fluorescent colorant injected in advance into the vicinity of a tumor is detected by use of a gamma-probe. A fiber coupler separates the low-coherence light emitted from the light source of an OCT portion (Optical Coherence Tomography) into a signal-light to be projected onto the sentinel lymph node and a reference-light whose wavelength is slightly shifted. The signal-light is projected onto the sentinel lymph node, and interference is caused between the signal-light reflected from a predetermined depth within the sentinel lymph node and the reference-light. A balance differential detector measures the intensity of the interference-light, and a cellular level ultra high-resolution optical tomographic image of the sentinel lymph node is obtained.
