摘要： The present invention relates to a phase modulating apparatus capable of highly accurately and easily correcting the phase modulation characteristic of a reflective electric address spatial light modulator even when a condition of input light is changed. In the LCOS phase modulating apparatus, an input unit inputs the condition of the input light, and a processing unit sets an input value for each pixel. A correction value deriving unit determines a correction condition according to the condition of the input light. A control input value converting unit converts the input value set for each pixel into a corrected input value based on the correction condition. An LUT processing unit converts the corrected input value into a voltage value, and drives each pixel by using a drive voltage equivalent to the converted voltage value.

摘要： Reading light (26) is phase-modulated by a phase-modulating spatial light modulator (12), the phase-modulated reading light (26) is Fourier-transformed, and an image of the Fourier-transformed reading light is focused on an output plane (24) to form an optical pattern. In this method, 0-order light in the phase-modulated reading light (26) is blurred on the output plane (24). As the 0-order light is blurred, the luminance of the 0-order light is reduced on the output plane (24). Since the 0-order light is not blocked, the shape of the optical pattern is not limited.
摘要翻译：读取光（26）由相位调制用空间光调制器（12）进行相位调制，对相位调制读取光（26）进行傅立叶变换，将傅里叶变换后的读取光的图像聚焦在输出平面（24）以形成光学图案。在这种方法中，相位调制读取光（26）中的0级光在输出平面（24）上模糊。当0阶光模糊时，0级光的亮度在输出平面（24）上减小。由于0级光不被阻挡，所以光学图案的形状不受限制。

摘要： The present invention relates to optical tweezers having a structure for realizing a great object-trapping force. The optical tweezers form an optical trap for trapping an object in, and in the vicinity of, each of plural trapping positions by converging output beams in each of the trapping positions. The optical tweezers comprise light emitting means for outputting a reading light, hologram generating means for generating an output hologram by arranging plural partial holograms two-dimensionally such that each partial hologram causes an output beam to converge in a corresponding trapping position, and a spatial light modulator for generating plural output beams, each of which has been phase-modulated in accordance with the output hologram, from the reading light which reaches the spatial light modulator. In particular, the hologram generating means arrange partial holograms belonging to a group which corresponds to one of the trapping positions such that the partial holograms are divided between two regions obtained by partitioning the output hologram in two, for example.
