Abstract:
PROBLEM TO BE SOLVED: To provide a fundus imaging apparatus that can correct optical aberration by an anterior component of eyes by optimizing a wavefront shape without using a wavefront sensor.SOLUTION: The fundus imaging apparatus includes a wavefront adjuster and a detector. The wavefront adjuster is configured to adjust a wavefront of a femtosecond pulsed laser beam incident on an ocular fundus to be examined. The detector is configured to detect fluorescence generated in a multi-photon excitation process by the femtosecond pulsed laser beam incident on the ocular fundus to be examined. The wavefront adjuster provides the fundus imaging apparatus for adjusting the wavefront so that an intensity of the fluorescence detected by the detector becomes maximum or an optical aberration correction apparatus.

Abstract:
PROBLEM TO BE SOLVED: To provide a microbead analysis method capable of highly accurately detecting fluorescence from a fluorescent material or the like used for labeling a target substance without requiring complicated preparation processes by excluding the effects of noise fluorescence caused by an identification pattern. SOLUTION: A microbead 1 is formed in a columnar shape comprising an upper surface 11 and a lower surface 12 opposed to each other approximately in parallel with each other and sides 13 continuous to these surfaces. The identification pattern is formed at least in either the upper surface 11 or the lower surface 12, and a solid phase of a substance having affinity to a substance to be detected is formed in the surface of the microbead 1. Fluorescence to be detected in the surface of the microbead 1 on the basis of the interaction between the substance to be detected and the substance having affinity to the substance to be detected is detected from a region including both of a region 112 in which the identification pattern is not formed among the upper surface 11 and the lower surface 12 and the sides 13 in the microbead analysis method.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of measuring the quantity of an in-vivo substance capable of measuring with easier operation than the usual method of measuring the quantity of in-vivo substance, and detecting even the in-vivo substance in a biological tissue. SOLUTION: A method provided for measuring the quantity of an in-vivo substance includes the steps of: irradiating an in-vivo substance with two near infrared femtosecond laser beams of different frequencies; detecting coherent anti-Stokes Raman scattering light emitted from the in-vivo substance due to coincidence of the frequency difference between the two near infrared femtosecond laser beams with a natural frequency of the in-vivo substance; and measuring the quantity of the in-vivo substance based on a peak intensity of an obtained Raman scattering spectrum.
