摘要： A living body function measurement method comprises separating a light from a low coherence light source into a signal light and a reference light, modulating a frequency of at least one of the signal light and the reference light, irradiating the signal light to an observation area of a living body sample, giving a stimulation to the living body sample from an outside of the living body sample, synthesizing the signal light via the observation area and the reference light and detecting a heterodyne interference signal, and measuring a living body function of the observation area by measuring a change in the heterodyne interference signal when the stimulation is changed.

摘要： An optical fiber made up of a core for propagating the light and a clad covering the core for confining the light propagated in the core. The optical fiber has a tapering protrusion at the apex for entrance and exiting of light. The optical fiber is used in a photon scanning tunneling microscope detecting the evanescent light localized in an area smaller in size than the wavelength of light on the surface of an sample as an optical probe disposed in proximity to the surface of the sample for scattering the evanescent light for detecting the scattered light. The optical fiber is optically coupled to an optical waveguide for constituting an optically coupled element. With this optically coupled element, a protrusion of the optical fiber operates as a collection unit for collecting the light propagated in the core. The light collected by the protrusion enters the optical waveguide.
