摘要： PROBLEM TO BE SOLVED: To display a three-dimensional image which is not realized by a conventional three-dimensional image display method, can be observed from any direction and in harmony with a background, and is natural.
SOLUTION: A transparent resin thin plate containing a light emitting substance which has an excitation wavelength in the invisible range and a light emission wavelength in the visible range is rotated at a designated speed to form a projection space, which is irradiated with excited light of the light emitting substance in synchronism with the position of the rotated transparent resin thin plate to draw a designated image in the projection space. The excited light is ultraviolet ray and therefore not observed. A moving picture can be drawn very easily by increasing the rotational speed. A color image can be drawn by using a transparent resin thin plate containing a plurality of light emitting substances differing in combination of light emission wavelength and excitation wavelength. The thin plate may be vibrated in order to form the projection space.

摘要： PROBLEM TO BE SOLVED: To obtain a large frequency shift quantity with high efficiency and to accurately shift a frequency to a position of an integral multiple of a specified frequency grid over a wide range. SOLUTION: After side bands (SB) are generated by modulating the phase of input light by an EOM 11 with a modulation frequency f m and a modulation index Δθ m1 and relative phases of the respective SBs are adjusted by a relative phase adjuster 13, the EOM 14 performs phase modulation with the modulation frequency f m and modulation index Δθ m1 to concentrate power on a specific SB nearby a degree Δθ m2 . Consequently, the frequency is shifted. After a relative phase adjuster 16 further performs relative phase adjustment having the opposite relation from the former relative phase adjustment, an EOM 17 performs phase modulation to cancel the phase modulation by the EOM 11 and then while the power is further concentrated on the specific SB, other SBs are suppressed. The shift quantity can be made greatly large since the frequency shift quantity depends upon the product of f m and Δθ m2 , and accurate variable shifting can be performed by controlling the Δθ m2 .

摘要翻译：要解决的问题：为了获得高效率的大频移量并且将频率精确地移动到宽范围内的指定频率格栅的整数倍的位置。解决方案：通过用调制频率f m 的调制指数Δθ m 的EOM11调制输入光的相位来产生边带（SB）并且通过相对相位调整器13调整各个SB的相对相位，EOM 14执行调制频率f m 和调制指数Δθ m1 的相位调制，以集中功率在特定的SB附近，Δθ m2 。因此，频率偏移。在相位相位调节器16进一步执行与前一相对相位调整相反的相位相位调整之后，EOM 17执行相位调制以消除EOM 11的相位调制，然后在功率进一步集中在特定SB上时，其他SB被抑制。由于变频量取决于f m 和Δθ m2 的乘积，因此可以使变速量大得多，可以通过控制Δθ< SB>平方米。版权所有（C）2007，JPO＆INPIT
