    • In some embodiments, the present invention relates to methods or suppressing edge ringing in images. For example, in some embodiments a method of processing an image to suppress ringing and broadened edges induced by image correction processing, includes high-pass filtering a first image to obtain a second image, processing said second image including applying non-linear apodization to said second image to obtain a third image, low-pass filtering said first image to obtain a fourth image, and combining the third image and the fourth image to obtain an output image, wherein the output image is characterized by having reduced edge-response sidelobes as compared to the first images. In some embodiments, the present invention relates to devices comprising means and/or modules to suppress edge ringing in images.

    • Systems and methods for three-dimensional imaging and viewing are disclosed. A method for generating a three-dimensional image may include producing a pattern in a spatial light modulator based on data representative of an image of an object, illuminating the spatial light modulator so as to yield a projection beam, masking at least one portion of the projection beam such that a portion of the projection beam is selected, and propagating the selected portion to an exit pupil so as to form a virtual 3-D image of the object when viewed at the exit pupil. An apparatus may include a projector comprising a spatial light modulator array that modulates the phase of light to produce a phase modulated beam that is projected to a viewer thereby forming a 3-D image of the object when viewed by the viewer, and processing electronics configured to extract phase information from a signal.
    • 公开了用于三维成像和观看的系统和方法。 用于产生三维图像的方法可以包括基于表示对象的图像的数据在空间光调制器中产生图案,照亮空间光调制器以产生投影光束,掩蔽至少一部分 投影光束使得投影光束的一部分被选择,并且将所选择的部分传播到出射光瞳,以便在出射光瞳上观察时形成物体的虚拟3-D图像。 装置可以包括投影仪,该投影仪包括空间光调制器阵列,其调制光的相位以产生投影到观看者的相位调制光束,从而在观看者观看时形成物体的3-D图像,以及处理电子设备 从信号中提取相位信息。
