摘要： A method of producing a big size holographic screen for projection of the stereoscopic or multiview 3-dimensional color images is proposed, where a narrow and elongate slit-shaped diffuser is recorded on the hologram as an object to ensure the well defined viewing zone forming in course of the image projection. As compared with the previous art the diffuser length is increased by the calculated value to provide undistorted color reproduction on whole screen surface. The parameters required for the recording of the holographic screen, including the position of a photoplate with respect to the diffuser, the position of a reference wave point source with respect to the diffuser, the distance from which an image is observed and so on are determined by consideration of the phase relationships between the reference, object, projector and reconstructed waves on the photoplate surface.

摘要： A video image F�k! is identified as a basis image and stored as a basis page S�k! in a holographic storage medium. A subsequent image F�k+n! is stored by recording in the medium a page S�k+n!=F�k+n!-a�k!F�k!, where a�k!.noteq.0 and preferably a�k!=1. The page S�k! is recorded with a reference beam R�k!, while S�k+n! is recorded with a reference beam R�k+n! orthogonal to R�k!. The basis page is reset whenever the average intensity of a page to be stored exceeds a predetermined threshold. An image F'�k! is retrieved by reading basis page S�k! and letting F'�k!=S�k!. Subsequent images F'�k+n! are retrieved as S�k+n!+b�k!S�k!, where b�k!.noteq.0 and preferably b�k!=a�k!=1. The page addition step is performed coherently, i.e. by accessing the medium with a reference wave function R�k+n!+b�k!R�k!. The coherent addition is achieved by using a compound phase-and-amplitude modulator in a phase-code-multiplexed system, and by simultaneously accessing the storage medium at two different angles in an angle-multiplexed system. Differential video compression leads to a reduction in interpage crosstalk and to a capacity increase in crosstalk-limited memories. Optical page-by-page addition allows fast readout and eliminates the need for a time-consuming electronic decompression step.
摘要翻译：视频图像F [k]被识别为基础图像并作为基本页S [k]存储在全息存储介质中。通过在介质中记录S [k + n] = F [k + n] -a [k] F [k]来存储后续图像F [k + n]，其中a [k] a [k] = 1。以参考光束R [k]记录页S [k]，而用与R [k]正交的参考光束R [k + n]记录S [k + n]。每当要存储的页面的平均强度超过预定阈值时，基页被重置。通过读取基本页S [k]并使F'[k] = S [k]来检索图像F'[k]。随后的图像F'[k + n]被检索为S [k + n] + b [k] S [k]，其中b [k] NOTEQUAL 0并且优选地b [k] = a [k] = 1。相干地执行页面添加步骤，即通过访问具有参考波函数R [k + n] + b [k] R [k]的介质。通过在相位码复用系统中使用复合相位和幅度调制器，并且在角度多路复用系统中以两个不同的角度同时访问存储介质来实现相干相加。差分视频压缩导致分组串扰的减少和串扰限制存储器的容量增加。光学逐页添加允许快速读出，并且不需要耗时的电子减压步骤。

摘要： A laser beam is reflected by a light beam scanning device and irradiated onto a hologram recording medium. On the hologram recording medium, an image of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin. The light beam scanning device bends the laser beam at the scanning origin and irradiates the laser beam onto the hologram recording medium. At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam on the hologram recording medium is changed with time. Diffracted light from the hologram recording medium produces a reproduction image of the linear scatter body on a light receiving surface of the stage. When an object is placed on the light receiving surface, a line pattern is projected by hologram reproduction light, so that the projected image is captured and a three-dimensional shape of the object is measured.

摘要： This invention relates to holographic image display systems. We describe an optical module for a holographic image projection system which displays a hologram (204) of a low spatial frequency portion of input image data on an SLM (SLM1) to form a holographically-generated intermediate real image which is in turn modulated (SLM2) by a higher spatial frequency portion of the image data (206), to display the image. The optical module comprises: at least one laser light source; a first spatial light modulator (SLM1) to modulate light from said at least one laser light source; intermediate optics (L4) to provide an intermediate real image plane at which a real image produced by a hologram on said first SLM is formed; a second SLM (SLM2) located at said intermediate real image plane to intensity modulate said real image; and output optics (L5,L6) to project an image of said intensity modulated real image; and wherein a resolution of said second SLM is greater than a resolution of said first SLM.
