摘要： In a wavelength swept light source using a polygon mirror in a well-known art, an oscillation wavelength roughly linearly varies in an upwardly slight convex shape with respect to time. On the other hand, in a wavelength swept light source of SS-OCT, the wavelength is required to vary so that a wavenumber (inverse of wavelength) linearly varies on a time axis. The wavelength swept light source of the well-known art has had a drawback that such wavelength variation cannot be implemented; non-linear distortion occurs in a resultant OCT image; and thereby, a point spread function cannot be kept sharp. According to the present invention, in a wavelength swept light source utilizing an electro-optic deflector including a KTN and so forth, such wavelength variation is caused that the wavenumber linearly varies with respect to a time axis by applying correction, which includes a sawtooth waveform as a main waveform and an exponential component of the sawtooth waveform, to the controlled voltage of the electro-optic deflector. The controlled voltage is controlled so that, as an oscillation wavelength to be swept is swept towards a longer wavelength side, a change rate of the oscillation wavelength is increased. With the controlled voltage, the oscillation wavelength varies more quickly as the oscillation wavelength is swept towards the longer wavelength side, and time variation in the oscillation wavelength is formed in a downwardly convex shape.

摘要： In a process of determining the surface shape of each of progressive multifocal lenses for use as lenses in eyeglasses, radii of curvature at main points are calculated, and then the surface is divided into a plurality of lattice sections, and then a curved-surface equation in the form of a bicubic expression is used for each section to determine the surface shape of the lens. A coefficient of each of the bicubic expressions is determined under a condition that continuation is established to curved-surface equations of sections adjacent at a boundary line between the sections to the derivatives of second order. Therefore, the surface shape of the lens obtained by the curved-surface equation for each section can be formed into a continuous and smooth surface. Since the curved surface can be determined for each section, a partial correction can easily be performed, if necessary. As a result, a progressive multifocal lens can be provided which exhibits smooth astigmatism curves and a large clear field of vision to meet a variety of specifications. Thus, lenses for eyeglasses each having a clear field of vision can be provided.

摘要： A progressive power lens is conventionally so designed that a distance portion and a near portion are linked together in a successive manner, and thus framing cannot be done in a manner as to fully achieve the best optical properties of the near portion. The present invention provides, on the other hand, a progressive power lens that is designed to make the near portion closer to an eyeball without impairing the optical properties of the progressive power lens. Accordingly, both the distance portion and the near portion can be framed with the ideal fitting, and the resulting eyeglasses can be less in distortion and fluctuation.

摘要： This semiconductor photodetector includes a photoabsorption layer, an n-type first semiconductor layer, and a p-type second semiconductor layer. The photoabsorption layer comprises an n-type first layer and a p-type second layer formed in contact with the first layer. The first semiconductor layer is arranged on the side of the first layer and has a shorter wavelength at a light absorption edge and a lower refractive index than in the photoabsorption layer. The second semiconductor layer is arranged on the side of the second layer and has a shorter wavelength at a light absorption edge and a lower refractive index than in the photoabsorption layer. When a predetermined reverse bias voltage is applied between the first and second semiconductor layers, the first layer is entirely depleted and the second layer is partially depleted.
