摘要： Brillouin scattered light is used to measure the distribution of elasticity and viscosity in a measurement object without contact and in a noninvasive and simpler manner. Measuring light emitted from a light source is directed from a light probe onto a measurement object, and scattered light is received by the light probe. A control computer analyzes the light spectrum of scattered light received by the light probe, calculates at least one parameter selected from the center frequency and the linewidth of the elastic wave scattered components as viscoelastic information, matches the viscoelastic information with the position of a target area in the measurement object, and outputs image information. The position information of the target area in the measurement object is acquired by photographing light spots of guide light with a camera provided to the light probe.

摘要： The optical tomographic image acquisition apparatus is based on FD-OCT. A detection unit 50A which detects interference light includes a lens 51, a reflection type diffraction grating 52A, a deflection unit 53, a lens 54), and a light receiving unit 55. The interference light collimated by the lens 51 is divided by the reflection type diffraction grating 52A. Light of each wavelength is output in a different direction according to the wavelength, deflected by the deflection unit 53, and focused on a light receiving surface of the light receiving unit 55 by the lens 54. The optical tomographic image of the object is acquired based on a correspondence relationship between a light radiation position for the object and a deflection angle by the deflection unit 53 and on optical power distribution detected by the light receiving unit 55.

摘要： An optical fiber and an optical fiber device, which can suppress generation of the stimulated Brillouin scattering while maintaining large nonlinearity. The fiber includes a central core which is made of SiO2 as a main component and contains Al2O3 at concentration of 15 wt % or more. The fiber is allowed to propagate only a fundamental mode and has an absolute value of chromatic dispersion of 5 ps/nm/km or less at a predetermined wavelength. The device includes the fiber having the above composition. The fiber guides first light and second light having different wavelengths to propagate therethrough such that the first light and the second light interact with each other by a nonlinear optical phenomenon during the propagation, thus causing the fiber to output the first light or the second light modulated by the nonlinear optical phenomenon or third light newly produced by the nonlinear optical phenomenon and having a different wavelength.
