摘要:
Provided is a scanning near-field optical microscope capable of obtaining in a highly sensitive manner, optical information having a spatial frequency higher than a spatial frequency corresponding to a wavelength of irradiation light. A scanning near-field optical microscope 100 according to the present invention includes: a light irradiating part 102 for emitting illumination light toward a sample 107; a light receiving part 112 for receiving light; a microstructure for generating or selectively transmitting near-field light, the microstructure being disposed on at least one of an emission side of the light irradiating part 102 and an incident side of the light receiving part 112; and an ultrahigh-wavenumber transmitting medium 108 for transmitting near-field light, the ultrahigh-wavenumber transmitting medium exhibiting anisotropy in permittivity or permeability.
摘要:
A blood-pressure sensor is constituted of an elastic body which is fitted to a blood-vessel outer wall, and a shape of which is deformed by force generated by pulsing motion of expansion and contraction of the blood vessel, and a plurality of nanosized particles dispersedly provided in the elastic body, and when the force is applied to the sensor in a state where the sensor is irradiated with light, the magnitude of the force is measured on the basis of intensity of scattered light from the particles or emission intensity of fluorescence from the particles, the intensity of the scattered light or emission intensity of the fluorescence corresponding to a change in distance between the particles.
摘要:
There is provided a blood-pressure sensor system wherein a blood-pressure sensor including a plurality of structures which induces surface plasmon resonance on a light-receiving plane of a photoelectric conversion element is attached to an outer wall of a blood vessel, in which if the blood-pressure sensor is deformed according to expansion or contraction of the blood vessel, an interval of layout of the structure is changed (widened or narrowed), so that an incident form of light with respect to the structures is changed to cause the output from the photoelectric conversion element to be changed. The output is measured as an open circuit voltage, and index calculation is performed, so that a blood pressure value is measured.
摘要:
A plurality of micro three-dimensional structure elements each having a movable structure fixed on a sacrifice layer, and fixation portions of the micro three-dimensional structure elements for the sacrifice layer are arranged into a film-like elastic body, and then the sacrifice layer is removed. Thus, a three-dimensional structure in which the individual micro three-dimensional structure elements are arranged independently of one another within the elastic body is manufactured.
