Title (EN) LIGHT CONTROL DEVICE AND LIGHT CONTROL METHOD
(FR) APPAREIL DE COMMANDE DE LUMIÈRE ET PROCÉDÉ DE COMMANDE DE LUMIÈRE
(JA) 光制御装置および光制御方法
Abstract:
(EN) A light control device (1) is provided with a light source (10), a prism (20), a spatial light modulator (30), a drive unit (31), a control unit (32), a lens (41), an aperture (42), and a lens (43).  The spatial light modulator (30) is of a phase modulation type, comprises a plurality of pixels which are two-dimensionally arranged, is capable of phase modulation in the range of 4π in each of the plurality of pixels, and presents a phase pattern for modulating the phase of light in each of the plurality of pixels.  The phase pattern is configured by superimposing a blazed grating pattern for light diffraction, the phase modulation range of which is 2π or less, and a phase pattern having a predetermined phase modulation distribution, the phase modulation range of which is 2π or less.
(FR) La présente invention concerne un dispositif de commande de lumière (1) qui est doté d'une source de lumière (10), d'un prisme (20), d'un modulateur spatial de lumière (30), d'une unité d'entraînement (31), d'une unité de commande (32), d'une lentille (41), d'une ouverture (42) et d'une lentille (43). Le modulateur spatial de lumière (30) est du type à modulation de phase, comprend une pluralité de pixels qui sont disposés en deux dimensions, est capable d'une modulation de phase dans la plage de 4 π dans chaque pixel de la pluralité de pixels, et présente un diagramme de phase permettant de moduler la phase de la lumière dans chaque pixel de la pluralité de pixels. Le diagramme de phase est configuré par la superposition d'un diagramme de réseau blasé pour la diffraction de la lumière, dont la plage de modulation de phase est inférieure ou égale à 2 π, et d'un diagramme de phase présentant une répartition de modulation de phase prédéfinie, dont la plage de modulation de phase est inférieure ou égale à 2 π.
(JA)  光制御装置1は、光源10、プリズム20、空間光変調器30、駆動部31、制御部32、レンズ41、アパーチャ42、レンズ43を備える。空間光変調器30は、位相変調型のものであって、2次元配列された複数の画素を有し、これら複数の画素それぞれにおける位相変調が4πの範囲で可能であり、複数の画素それぞれにおいて光の位相を変調する位相パターンを呈示する。この位相パターンは、位相変調範囲が2π以下である光回折の為のブレーズドグレーティングパターンと、位相変調範囲が2π以下である所定の位相変調分布を有する位相パターンとが重畳されてなる。
