摘要： Used as a propagation function is a half-plane propagation function which is restricted such that it has a value only within a half plane in a predetermined direction perpendicular to a propagating axis in a plane which is perpendicular to the propagating axis. According to a convolution integration with this function, the wavefront of object light on a hologram surface is determined, whereby hologram data is produced. Thus produced hologram is read out by means of readout light. After the light with a wavefront forming the conjugate image of the object to be viewed is blocked, the image of the object to be viewed is observed. Thus, a hologram, which has a high quality and from which the conjugate image is easily eliminated at the time of image reproduction, is produced while a recording device with a relatively low spatial resolution is used, and a three-dimensional form is displayed while the distortion with respect to the original image is reduced in thus produced hologram and the conjugate image is eliminated therefrom.

摘要翻译：用作传播函数的是半平面传播函数，其被限制为使得其在与传播轴垂直的平面中垂直于传播轴的预定方向上仅具有一个平面内的值。根据与该功能的卷积积分，确定全息图表面上的物体光的波前，从而产生全息图数据。由此产生的全息图通过读出光读出。在具有形成待观看对象的共轭图像的波前的光被遮挡之后，观察要观看的对象的图像。因此，在使用具有相对低的空间分辨率的记录装置的同时，产生具有高质量并且在图像再现时容易消除共轭图像的全息图，并且显示三维形式，同时在这样产生的全息图中减少了相对于原始图像的失真，从而消除了共轭图像。

摘要： A diaphragm having an aperture, the size of which is equal to or smaller than λf/p (λ is the wavelength, p is the imaging resolution, and f is the focal length of an imaging optical system) is arranged on the focal plane of the object space of the imaging optical system, and object light via the aperture is imaged by the imaging optical system. The object light via the imaging optical system and reference light are brought to interference to form interference fringes, and an image of the interference fringes is sensed. Using the hologram sensed in this manner, the image of the object to be sensed is reconstructed by adopting an imaging optical system equivalent to that upon imaging, and setting the positional relationship between the formed hologram and the imaging optical system in correspondence with that between the imaging optical system and the imaging surface upon imaging. In this way, a holography imaging apparatus which can vary the field of view and can sense a high-quality hologram using an imaging device having a relatively low spatial resolution is realized, and a holography display apparatus which can display an image by eliminating distortion with respect to the original image from a hologram sensed by the holography imaging apparatus of this invention is realized.

摘要： Young's interferometer (18) consisting of a single slit (14) and a double slit member (16), and an analyzer (20) are arranged along the axis of light to be measured. Parallel slits of the double slit member are provided with respective polarizers (16A,16B) whose polarizing directions are at ± 45° to the longitudinal direction of the parallel slits. The polarizing direction of the analyzer (20) is set in parallel with the parallel slits. The incident light passes through Young's interferometer (18) and the analyzer (20) to form an interference fringe, which is detected by an image detector unit (22). An image analyzer unit (24) produces an intensity profile of the interference fringe and determines the polarization state of the incident light, for instance, by comparing the produced intensity profile with profiles stored in advance.
