    Abstract: PURPOSE:To correct spectral characteristics in a wide wavelength region by making the output of a stimulation side spectroscope incident on a photodiode of known characteristics and correcting fluorescent stimulating spectra by using the output of this photodiode. CONSTITUTION:The dependency of the quantum efficiency (photocurrent/incident light quantity) on wavelength in the case of using a silicon photodiode as the photodiode 200 decreases in sensitivity at 275 and 370nm and is of the approximately constant value of 65 to 67% from 450nm up to 980nm. The fluorescent stimulating spectrum is proportional to the absorption spectrum if the yield of the fluorescent quantum is constant without depending on the stimulating wavelength and the intensity of the stimulating light is known. The stimulating light spectrally divides the light from a 150W Xe short arc lamp by a spectroscope 20 of 25cm focal length. The light emitted from a sample is condensed by two pieces of quartz lenses from the direction perpendicular to the stimulating light and is spectrally divided by the spectroscope 30 of 60cm focal length. The light is detected by a photoelectron multiplier T-photon counter. As a result, the absorption spectrum curve of a standard fluorescent soln. and the fluorescent stimulating spectrum curve agree with each other well.

    Abstract: PROBLEM TO BE SOLVED: To determine the dielectric constant in the tetrahertz area of a nonlinear optical crystal with a specific equation without using an optical system for far infrared rays by introducing the dielectric constant in the tetrahertz area from the transient response induced by pulses of ultra-short visible light. SOLUTION: The response of a sample is observed by the transient diffraction grating method. A well-known optical system used by the grating method can be used for the optical system. When two ultra-short light pulses are crossed in the sample, the sample is excited in a spatially periodic structure. When another ultra-short light pulse is fed, it is diffracted by the grating. The intensity of the diffracted light is recorded while the incidence time of this ultra-short light pulse is changed through a delay optical path, and the aging effect (responsiveness) of the grating is outputted. Such a vibration wave-form b(t) is determined that the square b(t) of its responsiveness reproduces the observed vibration component. The vibration wave-form b(t) is Fourier-transformed into b(ω). When b(ω) is substituted in the left side of the equation (1), the frequency dependency ε(ω) of the dielectric constant is obtained.

    Abstract: PROBLEM TO BE SOLVED: To attain accurate detection of the optical path, expanse and the like of laser beam sources with a wide ranging wavelength by forming a photodetecting surface provided on a substrate with a KLN microcrystal body having a second harmonic-generating function of non-linear optical effect to allow adaptation to the laser beam sources. SOLUTION: Alumina powder mixed with an adhesive is applied on the surface of a substrate 1 such as aluminum plate or quartz glass plate to form and dry a reflection preventing film 3. Then, microcrystal powder of potassium lithium niobate (K3 Li2 Nb5 O15 , so-called KLM) or 5 nitro 2 aminotoluene [CH3 C6 H3 (NO2 )NH2 , so-called NMK] is mixed with an adhesive to and applied at one end part of a preventing film 3 to form a photodetecting surface 3. This attains not only recognition of a laser beam wavelength from luminescent color but also adaptation to light with a wide wavelength range with one detector. This also allows the accurate determination of the shape and the position of a laser beam thereby improving resistance to damage by laser.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical modulation method which resolves the degradation of the high repeating performance of an optical modulation element, the degradation of an element material and the change of the characteristic due to light absorption which are generated because the exciting state of a J-assembled body is generated because an operating light LPU has used a light having a wavelength which is to be absorped by the J-assembled body conventionally and whose operating speed is the order of femto secs. in low light intensity and the device therefor. SOLUTION: In an optical modulation method which makes pulse widths (tp) of a signal light and an operating light to be shorter than the phase mitigating time (T2) of the polarization of a PIC J-assembled body and also the operating light is made to be incident on an optical modulation element 11 by being delayed by Δt time from the incident time of the signal light in order to perform the intensity or the phase modulation of the signal light by making a coherent and pulse shaped signal light Lpr and the operating light Lpu having a large light intensity incident on the element 11 using the PIC J-assembled body, this method uses a non-resonance light which is not absorbed by the element 11, provided tp

    Abstract: PURPOSE:To measure the concn. of the antigen in a specimen with high accuracy by measuring the size of the grain size of the agglutinated matter generated by the conjugation of antibody sensitized polymerized liposome or antibody sensitized polymerized micell and the antigen in the specimen. CONSTITUTION:The antibody sensitized polymerized liposome or antibody sensitized polymerized micell subjected to antibody conjugation is formed by polymerizing the liposome or micell formed of 1 or >=2 kinds of polymerizable compds. among polymerizable surfactants and polymerizable lipids and the antibody chemically modified by one molecular chain or both molecular chains of polymerizable-non-polymerizable molecular chains. The specimen contg. the antigen is then added to a liquid dispersion contg. the antibody sensitized polymerized liposome or antibody sensitized polymerized micell to induce an agglutination reaction by an antigen-antibody reaction. The size of the agglutinated matter formed in such a manner is measured by a light scattering measuring instrument. The concn. of the antigen in the specimen is measured from the size of the grain size of the agglutinated matter.
