Abstract:
(EN) The present invention provides an optical device, comprising a light source, a first spatial light modulator, and a second spatial light modulator. The light source emits incident light to the first spatial light modulator and the second spatial light modulator; the first spatial light modulator and the second spatial light modulator modulate the incident light and output the modulated incident light as output light, and the output light outputted from the first spatial light modulator and the second spatial light modulator are superimposed to form a target light field. According to the optical device provided by the present invention, two spatial light modulators are utilized to form a target light field; thus, the amplitude and phase of the light field can be simultaneously restored with high quality, and high-quality imaging can be performed at different imaging distances.
(FR) La présente invention concerne un dispositif optique comprenant une source de lumière, un premier modulateur spatial de lumière et un second modulateur spatial de lumière. La source de lumière émet une lumière incidente vers le premier modulateur spatial de lumière et vers le second modulateur spatial de lumière ; le premier modulateur spatial de lumière et le second modulateur spatial de lumière modulent la lumière incidente et transmettent la lumière incidente modulée sous forme de lumière de sortie, et les lumières de sortie émises par le premier modulateur spatial de lumière et par le second modulateur spatial de lumière se superposent pour former un champ lumineux cible. Grâce au dispositif optique que propose la présente invention, deux modulateurs spatiaux de lumière servent à former un champ lumineux cible ; ainsi, l'amplitude et la phase du champ lumineux peuvent être restaurées simultanément selon une qualité élevée et une imagerie de haute qualité est possible à différentes distances d'imagerie.
(ZH) 本发明提供一种光学装置,包括光源、第一空间光调制器、第二空间光调制器,所述光源向所述第一空间光调制器和所述第二空间光调制器发射入射光线;所述第一空间光调制器和所述第二空间光调制器调制所述入射光线并将调制后的所述入射光线作为输出光线输出,输出自所述第一空间光调制器和第二空间光调制器的输出光线相互叠加形成目标光场。本发明提的光学装置由于使用了两个空间光调制器来形成目标光场,所以能够同时高质量的还原光场的振幅和相位,可以在不同成像距离上进行高质量成像。
