摘要： Light emitted from a light source is divided into measuring light and reference light. The reflected light from the object and the reference light are superposed. Interference light of the reflected light and reference light which have been superposed is detected. Intensities of the reflected light in a plurality of positions in the direction of depth of the object are detected on the basis of the frequency and the intensity, and a tomographic image of the object is obtained on the basis of the intensity of the reflected light in each position in the direction of depth. A compensating signal is obtained by removing the spectral components of the measuring light from an interference signal obtained by detection of the interference light, and the compensating signal is provided for detection of the intensities of the reflected light after a Gaussian transform.

摘要： A laser annealing system and apparatus, which includes a laser light source, which emits a laser beam through an a-Si layer on a substrate, an optical unit which forms an optical path along which the laser beam is transmitted through a subject to be annealed, and a first reflecting component, which reflects the laser beam that has been transmitted through the subject so that a direction of the laser beam is reversed along the optical path along which the laser beam is transmitted through the subject, to irradiate the subject.

摘要： Low coherence light is divided into measuring light and reference light. The measuring light is collected to be projected onto an object of measurement. Intensities of the reflected light in a plurality of positions in the direction of depth are detected by carrying out a Fourier analysis on each channeled spectrum obtained by decomposing the detected interference light into frequency components. The optical path length of the reference light is stepwise changed to adjust the optical path length within the focusing range of the measuring light. A plurality of pieces of data representing the intensity of the reflected light are obtained in a plurality of positions in the direction of depth each time the position of the focusing range changes, and data on the position in the direction of depth where the measuring light is in the focusing range is extracted out of the pieces of data.

摘要： A light source unit emits a laser beam, of which the wavelength is swept at a predetermined period. The central wavelength λc of the sweep and the wavelength sweep width Δλ of the laser light beam satisfy the conditions: λc2′/Δλ≦23, λc+(Δλ/2)≦1.2 μm, and λc−(Δλ/2)≧0.98 μm. A light dividing means divides the laser beam into a measuring light beam, which is irradiated onto a measurement target via an optical probe, and a reference light beam that propagates toward an optical path length adjusting means. A multiplexing means multiplexes a reflected light beam, which is the measuring light beam reflected at a predetermined depth of the measurement target, and the reference light beam, to form a coherent light beam. A coherent light beam detecting means detects the intensity of the multiplexed coherent light beam. Image processes are performed, an optical tomographic image is displayed.

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： An endoscope apparatus that has an OCT function and can efficiently obtain an optical tomographic image is provided. An image of an area within a body cavity is displayed on a monitor, and an operator uses a pen-type input to specify a point thereon. An aiming-light is projected onto the body cavity and displayed on said monitor as a bright point, and a coated tube of an OCT probe is slid and rotated by a scanning controller so as to align the aiming-light with the point. A scanning-area setting means sets a ring shaped scanning area when the aiming-light and point are aligned. The scanning area is scanned with a signal-light, and an optical tomographic image is obtained and displayed on a monitor. An optical tomographic image can be efficiently and expediently obtained without the need to manually direct the irradiation position of the signal-light to a desired scanning area.

摘要： Amplified spontaneous emission light, which is low coherence light radiated out from an optical fiber doped with a light emitting material when excitation energy is applied to the optical fiber, is divided into signal light and reference light. A frequency of the reference light is shifted to a frequency slightly different from the frequency of the signal light. A tomographic image of a measuring site is acquired from an intensity of interference light formed by the signal light reflected from the measuring site and the reference light.

摘要： A homodyne interference system splits first and second light beams from a common light source and causes the first and second light beams to impinge upon an irradiating point of an organism at different directions. An optical heterodyne system splits a third beam from the common light source and imparts a frequency shift to the third beam. The outputs of the homodyne and heterodyne systems combine to permit extraction of a beat component of the homodyne system at a high SNR level. The output of the homodyne and heterodyne system are output as an image, which may be timed to a phase timing mechanism to provide an improved output.
