摘要： PROBLEM TO BE SOLVED: To provide a variable optical filter device whose filter characteristics may be arbitrarily changed.SOLUTION: Incident light from an optical fiber 11 is allowed to enter a frequency dispersion element 15. The frequency dispersion element 15 disperses the incident light in a direction in accordance with a frequency of the incident light and supplies the dispersed light to a lens 16. The lens 16 develops the incident light into a linear shape on the xy plane in accordance with the frequency. A frequency selection element 17 has a pixel structure in which pixels are arranged in a frequency dispersion direction and places, in a reflection state, a pixel disposed in a position corresponding to a frequency to be selected. Light of the frequency thus selected by the frequency selection element 17 is output through an optical fiber 14 via one path. When the reflection characteristic of the frequency selection element 17 is varied for each pixel, characteristics of an optical filter may be arbitrarily changed, resulting in changing a pass bandwidth and shifting a frequency of the filter.

摘要： PROBLEM TO BE SOLVED: To provide an optical filter that allows each channel of a WDM signal repeating at specified frequency intervals to have the same optional spectrum shapes and phase characteristics. SOLUTION: An input signal is input to a dispersing element 16 through an optical fiber 11, a circulator 12, and an optical fiber 13. The dispersing element 16 disperses and emits the WDM signal for each channel within ranges of predetermined angles according to frequency variations in the respective channels. Dispersed light of frequencies dispersed within the ranges of the predetermined angles for each channel are condensed by a lens 17, and the phase characteristics and spectrum intensities of the condensed light are varied by a phase control plate 18 and a light intensity control plate 19. The light is guided to an optical fiber 15 through the same path. Consequently, the optical fiber is provided which performs the same operation for each of channels of the WDM signal.

摘要： PROBLEM TO BE SOLVED: To clearly display sectional images of a caries region of a tooth and of a periodontal pocket.
SOLUTION: A scattering suppressant is previously applied to the surface of a tooth, and after that, tomographic images of the tooth and the peripheral area are displayed by an optical interference tomographic image diagnostic apparatus. As the scattering suppressant is previously applied, scattering of light on the surface of the tooth is prevented and the light penetrates into the tooth, and therefore, a clear sectional image can be displayed. Further, the contrast of the periodontal pocket and the caries region to other regions is intensified, so that the clear image can be provided. With this structure, the caries region of the tooth and the periodontal pocket can be accurately, objectively, non-invasively and non-destructively determined, and as a result, accurate treatment and preventive measures can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a wavelength scanning laser light source which is capable of changing the oscillation frequency, at a fixed varying speed. SOLUTION: A polygon mirror 24 which constitutes a wavelength variable filter is rotated at a constant speed by a driving section 25. A diffraction grating 27 is located at a position on which an incident beam reflected by the polygon mirror 24 falls. The grating pitch of the diffraction grating 27 is changed with respect to the incident position so that selected frequency changes, at equal speed with respect to the incident light which is incident at an equal angular speed. Thus, the oscillation frequency can be changed at a fixed speed. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable wavelength filter in which an arbitrary wavelength selection characteristic is easily available. SOLUTION: Light is made incident on a diffraction grating 13 and output with a distribution of angles different for every wavelength. The distributed light is turned into a belt-shaped light with a lens 14, and made incident on a mirror substrate 15 having selective reflection regions 17-1 to 17-x. By moving the mirror substrate 15 in a direction different from the distribution direction of the belt-shaped light, the light having either one wavelength is reflected. And the light returned back to the diffraction grating 13 is reflected to the original incident direction of light. Thus, the variable wavelength filter, in which the light having an arbitrary wavelength is selected by moving the mirror substrate 15, is achieved. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable-wavelength laser light source which can change wavelength in a wide band in a single mode without mode hop.
SOLUTION: An external resonator is comprised of a semiconductor laser 11 and a diffraction grating 14, and an optical deflector 13 is provided therebetween. The optical deflector 13 deflects a light by a signal from the outside, so as to change a grating pitch of the diffraction grating 14 at the incident part of the light. Thus, a change in wavelength of the external resonator mode is synchronized with a change in wavelength by the diffracted wavelength of the diffraction grating. As a result, wavelength can be scanned in a single mode without mode hop.
