<P>PROBLEM TO BE SOLVED: To perform high-speed detection of high absolute wavelength resolving power, high relative wavelength resolving power and high paired-wavelength sensitivity using a small-sized inexpensive device. <P>SOLUTION: An excitation wavelength converter 12 that is an optical sensor is emits excitation 20, for example, light 24 having photon energy peak values that correspond to the content of a wide-wavelength region light illumination, that is, narrow-wavelength region light within a photon energy region. A propagation member 30 converts the emitted light 24 of a converter 10 to diffused light 32 to propagate a diffused light 32 to the transmission structure 40 in a light-detecting assembly 34. The multilayered transmission structure 40, having lateral modification in photon energy transmission characteristics discharges photons 46 and 48 from regions 42 and 44 that are different, corresponding the photon energies λa and λb of the light 32 received by the incident surface thereof. Photon quantity difference or the photon discharge position in the structure 40 is detected by the mutual detection results of the photon discharge quantities at the positions 52 and 54 of a photon-detecting member 50 and the wavelength change or photon energy distribution of the light 24 is calculated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
