An optical measuring method and an optical measuring apparatus are capable of obtaining the true mean time delay of a light waveform within a short time for the purpose of obtaining information on the internal structure of an object. Calculations include a first mean time delay when the light path includes the object, a second mean time delay when the light path does not include the object, and a subtraction of the second mean time delay from the first mean time delay to obtain a true mean time delay.

A processing unit notifies a drive unit of a designated number N (=1, 2, . . . ) The drive unit supplies a drive signal of a frequency f.sub.0 to a target measurement device, and supplies a modulation signal of a frequency N.multidot.f.sub.0 +.DELTA.f to a light source. In this state, an intensity-modulated light beam is emitted from a light source, incident on an E-O probe through an optical system including a PBS and a wave plate, influenced by a periodical voltage waveform generated at a target measurement portion at a fundamental period 1/f.sub.0 to modulate the polarized state, and output from the E-O probe. The optical signal whose polarized state is modulated is input to a photodetector after a polarization direction is selected by the PBS, and heterodyne-detected. The processing unit reproduces the waveform of the voltage signal generated at the target measurement portion by Fourier transform on the basis of the obtained calculation of photodetection signal and displays the waveform.
摘要:
A method of measuring internal information in a scattering medium and an apparatus for the same of the present invention measure internal information in the scattering medium by measuring light diffused during propagation in the scattering medium at outside of the scattering medium while receiving the influence of the scattering and absorption, and performing arithmetic processing to the measured values. At this time, the three or more kinds of the detected signals (measured values) detected at a plurality of distances between the light incident position and the photodetection point for the light having a plurality of predetermined wavelengths are processed by utilizing dependencies of the behavior of light diffused during propagation in the scattering medium and the resulting signal, i.e., a photodetection signal on characteristics such as a scattering constituent, or an absorption constituent in the scattering medium and their concentration. If the measurement is performed at a plurality of wavelenghts on an object to be measured, a ratio of absorption coefficients and a ratio of concentrations of specified absorptive constituents in scattering medium can be measured.

At this time, the three or more kinds of the detected signals (measured values) measured at three or more different kinds of distances between the light incident position and the photodetection point are processed by utilizing dependencies of the behavior of light diffused during propagation in the scattering medium and the resulting signal, that is, a photodetection signal on characteristics such as a scattering constituent, or an absorption constituent in the scattering medium and the concentration. The measured internal information is the absolute value of a scattering coefficient or a transport scattering coefficient of the scattering medium, and the information associated with a specified scattering constituent or a specified absorption constituent can be measured by processing the measured internal information.
摘要:
A wavelength of light emitted from a semiconductor laser is shifted to a shorter wavelength with wavelength converting means and the resulting light of a shorter wavelength is applied to a sample. Upon exposure to the light of the shorter wavelength, the sample emits light of interest and its waveform is measured with measuring means. Fundamental wavelength laser light which passes through the waveform converting means is outputted therefrom in synchronism with the light of a shorter wavelength and detected by a first photodetector. The waveform of the light of interest can be measured correctly on the basis of an output signal from the first photodetector.
