    摘要: A fluorescent member includes a plurality of particles dispersed in a medium. Each particle includes a core and a coating layer covering the core. The core is formed of a semiconductor which absorbs excitation light and emits light of a wavelength different from that of the excitation light. Each particle is made to have a particle size for causing Mie scattering with respect to the excitation light. Thus, a fluorescent member excellent in light conversion efficiency can be obtained.

    摘要: A system for transmitting information with a coherent beam being propagatable in the air is arranged to include a transmitting device having a modulator and an emitting circuit and a receiving device having a generator, a mixer, a frequency discriminating circuit, and reproducing circuit. The modulator modulates a reference light frequency (wavelength) or phase of a coherent beam to be emitted from a light source according to the signal. The emitting circuit emits the modulated beam as a divergent beam having such a power density as being safe to human eyes. The generator generates a coherent locally oscillated beam. The mixer mixes the signal beam with the locally oscillated beam and photoelectric-converts the mixed beam. The frequency discriminating circuit frequency-discriminates the a.c. component of the photoelectric-converted output. The reproducing circuit reproduces a signal from the output of frequency discriminating circuit. Any one of the transmitting device and the receiving device has a function of keeping a relative light frequency difference (wavelength difference) between the signal beam and the locally oscillated beam constant.
