摘要： A wavelength swept light source 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.

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.
摘要翻译：在已知技术中使用多面镜的波长扫描光源中，振荡波长相对于时间大致呈线状变化，呈向上略微凸起的形状。另一方面，在SS-OCT的波长扫描光源中，要求波长变化，使得波数（波长的倒数）在时间轴上线性地变化。已知技术的波长扫描光源具有不能实现这种波长变化的缺点; 在所得的OCT图像中发生非线性失真; 因此，点扩散功能不能保持尖锐。根据本发明，在使用包括KTN等的电光偏转器的波长扫描光源中，通过应用校正导致波数相对于时间轴线性变化的波长变化，该修正包括锯齿波形作为锯齿波形的主波形和指数分量，与电光偏转器的受控电压。受控电压被控制为使得随着扫描的振荡波长向较长波长侧扫过，振荡波长的变化率增加。利用受控电压，随着振荡波长向较长波长侧扫描，振荡波长变化更快，振荡波长的时间变化形成为向下凸的形状。

摘要： A variable focusing lens is provided that can change the focal length at a high speed. The variable focusing lens includes: a single crystal electrooptic material having inversion symmetry; a first anode formed on a first surface of the electrooptic material; a second cathode provided to have an interval to the first anode; and a first cathode and a second anode that are formed on a second surface opposed to the first surface and that are formed at positions opposed to the first anode and the second cathode. An optical axis is set so that, when light enters through a third face orthogonal to the first surface, light exists through a fourth surface opposed to the third face. A voltage applied between the first and the second pair of electrodes is changed to thereby change the focal point of light emitted from the fourth surface of the electrooptic material.

摘要： To provide a variable-focal length lens capable of altering its focal length at high speed. The variable-focal length lens has an electrooptic material and electrodes formed on an incident surface of light and on an exit surface of the light of the electrooptic material. An optical axis is set so that the light is inputted into a gap where the electrodes of the incident surface are not formed and is outputted from a gap where the electrodes of the exit surface are not formed. A focus of the light that is transmitted through the electrooptic material becomes variable by varying an applied voltage between the electrodes of the incident surface and the electrodes of the exit surface.

摘要： A wavelength converter implements high speed, high efficiency, low noise wavelength conversion without performing high voltage poling of a crystal, and enables switching and modulation of converted light in response to an electric field. A KLTN crystal, includes a deposited-gold electrode within its incidence plane, and is connected to a DC power supply via a copper wire. The crystal material is composed of KTa1-xNbxO3 and/or K1-yLiyTa1-xNbxO3. A polarizer controls the polarization of the fundamental wave in the direction parallel to the electric field, and launches it into the electrode of the KLTN crystal. The KLTN crystal, rotating on an axis in the direction of the electric field, launches only part of the generated SHG light with the same polarization direction as that of the incident light into a photo multiplier tube through a polarizer.
