Description

200825455 九、發明說明: 【發明所屬之技術領域】 本案為一種具有用來在某個觀察者平面裡追蹤至少一 個虛擬觀察者視窗的方法與顯示裝置,其中的觀察者平面 裡至少存在著一個觀察者。另外,本案也會與用來建立 產生此一方法的顯示裝置有關。 【先前技術】 本案所提出的具有用來在某個觀察者平面裡追蹤至少 一個虛擬觀察者視窗的方法與顯示裝置,主要是用來將二 與/或三維物件顯示到一或多個觀察者,特別是全像影像顯 示裝置。然而,本案也可以應用在3D立體顯示裝置。 在以前曾經公開發表過的文獻裡,類似具有光調校模組裝 置的全像影像顯示裝置,其中光調校模組裝置的全像影像 其富利葉轉換會呈像在某個觀察者的眼睛瞳孔上。這樣 的顯示裝置其出口瞳孔將會貼緊於某個觀察者眼睛的瞳孔 上,並且作為參考用的觀察者視窗。在顯示裝置裡的最 後光學元件,可以在光線行進的方向中被看見並且位於觀 察者之前以作為螢幕之用。此時我們假設此一螢幕是一 個聚焦光學元件。 如果在某個全像影像顯示裝置裡觀察者視窗與眼睛的 瞳孔一致,則觀察者將可以以在一個重組圖集中看到一個 物件的重組外觀,且在觀察者視窗與螢幕之間擴張展延。 然而,如果觀察者靠著邊緣或沿著顯示裝置的光學轴移動, 200825455 則觀察者視窗將不能再與觀察者的眼睛瞳孔一致。如此 將會產生重組外觀的殘影插圖,且只會被部份看見或完全 看不見。 藉由之前所提出的文獻或方法,為了避免當觀察者以 侧面方向的方式移動而產生前述的重組外觀殘影插圖,我 們將需要一個位置偵測系統以偵測觀察者眼睛的位置。 藉由一個追蹤單元之助,如果觀察者移動到另外一個位置 時觀察者視窗將可以被追蹤到觀察者的眼睛。觀察者視 窗也會在觀察者平面裡從侧面方向被追蹤。關於這個問 題之前已經有很多知名的文獻公開發表過了。 舉例來說, 迄今仍未公開的專利文件DE 10 2005 023 743.6說明了一 種追宗觀察者視窗的可行方法。藉由此一文件,觀察者 視窗可藉由位於光調校模組裝置之後的折射元件之助而受 到追蹤,並且可以在光線進行的方向中被看見。 【發明内容】 然而,如此的排列配置所伴隨產生的缺點在於,因為 追蹤元件被安排在光調校模組裝置與螢幕之間,而且顯示 在螢幕上的影像是傾斜的,所以此一影像將會隨著觀察者 位置的改變而跟著被扭曲。如此也會導致螢幕上的影像 被歪斜扭曲,且重組後的影像也無法真實地展現出來。 然而,沿著顯示裝置的光學軸來追蹤觀察者視窗,也 就是順著朝向螢幕或背著離開螢幕,和側向追蹤比較起來 需要有不同的方式。我們必需確認觀察者視窗確實是沿 著光學軸的方向在進行,因為不如此的話重組後的外觀將 200825455 會出現殘影插圖。另外,光調校模組裝置的影像必需永 遠地以相同的方式被呈像到螢幕上且不能有任何改變,且 無論觀察者與螢幕之間的距離。這表示光調校模組裝置 的影像,類似像螢幕上局部給某個觀察者的位置a,必需 在螢幕上指定給某個觀察者的位置b,且出口瞳孔必須被 顯示出來。 一種可以同時用來作側向與軸向追蹤的方法如日本專 利申請文件編號第09068674 所詳述,其中還包括細部 圖解說明。在此文件中詳細說明了藉由二個空間光調校 模組之助而用來作三維外觀展示的一個電子全像影像顯示 器,它描述了一個用來將從光調校模組的光投影到觀察者 眼睛的傾斜鏡面元件。每一個具有相對應之全像影像的 光調校模組將會為了觀察者的某隻眼睛而被擴張。三維 外觀會在傾斜鏡面元件附近或之上的區域中被重組。任 何觀察者的移動都會被一個位置偵測系統所偵測且此傾斜 鏡面元件也會依其水平或垂直軸而作旋轉以追隨觀察者眼 睛的新位置。在此同時,對應於新觀察者位置的三維外 觀會在全像影像中被修正。另外,還有光線的侧向追蹤, 某一轴向的追蹤,即沿著顯示器的一個光學軸,都在圖中 有詳細的說明。藉由觀察者眼睛的新位置,光線會順著 朝向或背離三維外觀的方向被追蹤。如此的追蹤方式會 藉由修正改變兩個光調校模組之間的側向距離來達成。 也因此光線可以碟實地擴展到某隻確定的眼睛上。藉由 某個觀察者眼睛的位置,新的眼睛位置可藉由位置偵測系 統來作偵測而得,而光調校模組彼此之間會以侧向的形式 200825455 關係來作排列配置,也因此光線將可以沿著光學軸來被追 蹤,而重組後的外觀也將因此而永遠能被觀察者的眼睛所 看見。 如果我們使用上述的追蹤方式,則殘影插圖的問題將 不會再成為困擾,這是因為重組後的外觀非常小的緣故。 另外,藉由此一方法光線將會在經過光調校模組裝置的調 t修正之後被折射。如此將會導致影像被扭曲或傾斜。 還有,藉由專利申請文件編號JP 09068674,並沒有形成 所疋義的觀察者視窗以利後續的追蹤,但是其餘的可視區 ,都會被追蹤。H步地,系統_孔在此並不會與 硯察者眼睛的瞳孔-致,4旦卻會落在冑察者眼睛與重組後 夕卜觀之間。h果我們需要—個較大的重組外觀,則此一 專利所提出的方法將無法適用。 ^㈣此,本案提丨_個具有追蹤虛_察者視窗機 祀㈣輩日偭41衣置,而其中所謂的方法與裝置將能夠 1早且便利地在侧面方向與軸向裡追蹤觀察者視窗。 項目藉Λ本案所提出的方法與裳置,我們可以達到如申請 項目1與11所列的功能。 月 藉由本案所提出的方法 述,為-個顯示裝置,特別用、如申請項目1中所 當觀察者移動到另-個位置王像影像顯示裝置,以便 者視窗,而詳細執行細節如以:以追縱至少—個虛擬觀察 觀察者存在於某—觀察=所述,且此時至少有-個 統以在觀察者平面裡偵測:。#在—個位置债測系 規察者的眼睛位置並將偵測到的 啟=貝Γ傳送給—個控制單元。此〜i ΐ動一,礙單^藉㈣的觀*者:_單元接著將會 L°i糟由本案所提出的這個方法斑壯置來追蹤觀察者視 二:】調校修正發光光束的光學路徑-置,觀察者視窗可 二個〇/ 1切校模組裝置之間的:i U及在介於1光 =先學元件來_ Φ :單元裡使用至少 由追縱單元來C =保持不變。ϋ蹤可4 1,調校模組裝置:前,被讀配置在顯示裝置裡心 向的追縱。視;:::隨著觀察者的移動而作側向邀軸 窗會藉由追改變的方式不同,觀察者 車由向同時被^在側向或在軸向方㈣,或甚至側^ J中的=:ί : 的|f:本與案裝置可以提供許多優點。 g之助,我們將能心三維外觀察者視窗追礙 ::,特別是在外觀重組的情升;;展現時伴隨產生的殘影 ::硯展現的全貌且沒規祭者將:以看到 ^維外觀的方向或背離的=制,即使觀察者是朝 口瞳孔永遠與觀察者動時,這是因為系統 至内,可以在螢幕後面的任何::目里孔-致。另外,瑩幕 ,在光線行進的方向中 ^固定常態的形式被觀察 置破觀察到。特 #規$到,以及在觀察者所在的 :率或側向擴張所帶來::在光調校模組裝置上之光線的 b牌可以在簡易的情 =,_將會—直維持不變。如 見二維的外觀,並且深入眼睛 200825455 與大腦的内部。 軸向裡作追縱。、有,减察者視窗將可以同時在侧向與 本案所提出的方法與裝置 的側面方向裡且光線以某個角度落在^^在觀察者平面 或發散的集合光虔的郴齐贫 ^ λ 種收斂 在追蹤單元裡=::=校:=上。藉由 ==察者視窗也會順著顯示裝== 改變。…原始位置點也跟著觀察者的位置而有所 置被提出的方法,我們還可以將光調校模組裝 + 像〜像之一個昌利葉轉換被呈像到至少一 親=白勺眼睛上時,將因此而形成一個觀察者視窗。 猎由本案所提出的顯示裝置以及所申請的第11項專 所述之機制返可以達到另外的目的,特別是運用在 硯:〒組t。·由本案所提出的顯示裝置主要是應用 在:、倾/或三維外觀展示的全像影像顯示裝置上。此一 ::裝置包含了至少一個光源與至少一個光調校模組裝置, 可利用此一即將要重組的外觀來調校連續入射光線。 2 曙 2M55 另外,此〜顯示譽 勹 察者的觀察者、匕擴一個用來在存在有至少一個觀 統。還有,裡^則觀察者眼睛位置的位置偵測系 個存在了至少系統,即一個螢幕與一個用來在某 察者視窗的追:::察者:觀察者平面裡追蹤-個虛擬觀 此追蹤單元將合 ’也㊂包含在此一顯示裝置裡。因 並且可以在在光源與光調校 模組裝置之間, 外的位置時將向中被看見,當觀察者移動到另 或軸向追礙,以曰"、“作為虛擬觀察者視窗的侧向與/ 會有任何的改變。侍在螢幕上之光調校模組裝置的影像不 藉由本案所提出之顯壯 利文件所述之機制為最佳:二置以及所申請的第1項專 觀察者的觀察者韻齊、置方式。存在至少有一個 殘影插圖的二维盘=是觀察者平面)可以藉由沒有 向(也就是餐光學二重追:之助來作側向的追縱與轴 校模組農置的影像並不另外,在發幕上光調 以影像是不會傾斜歪曲^扭曲或傾斜的形態來顯示,所 組將可以被見,還有蕤.如此一來某個外觀的實際重 义的光線其倍器將== 得簡單者視窗的追縱能以最少的元件機制卻I變 在本案所提出的顯示裝置中 它被安排配置在光調校模組裝置^=統,殊優點為s 裡被看見,是―轉11且穩定m切行埃的 靜滤光學系統之助在發幕 」、也由於此〜 愛綦上先调杈模組裝置的影像將不♦ 200825455 被扭曲或傾斜。 藉由本案所提出的具體實施範例其最大的優點在於我 們所產生提供的觀察者視窗將會大於觀察者眼睛的瞳孔大 小,其中眼睛瞳孔主要是用來過濾富利葉頻譜。如此一 來富利葉頻譜將可以被濾除且顯示裝置的設計也將變得更 加%疋堅固。為了避免富利葉頻譜的週期連續發生我 們可以利用變跡法(apodisation)以作為特殊的頻率濾波 器。這種方式到目前為止最常用的範例為已經公開發表 過的專利文件DE 10 2006 030 535.3,它也可以讓本^戶^ 提出的方法得以避免週期連續的發生。 另外還有個優點就是在追蹤單元理再提供一個附加投 衫系統以便能夠在某一發光光束的光學路徑裡修正像差。 本案所提出之另一 ,申請項目來作定義。本案所提出之具體實施範例 藉由以下的詳細說明與圖示來作更進一步的瞭解。士电200825455 IX. Description of the invention: [Technical field to which the invention pertains] The present invention is a method and display device having at least one virtual observer window for tracking in an observer plane, wherein at least one observation exists in the observer plane By. In addition, the present case is also related to the display device used to create this method. [Prior Art] The method and display device proposed in the present invention for tracking at least one virtual observer window in a certain observer plane is mainly used to display two and/or three-dimensional objects to one or more observers. Especially for holographic image display devices. However, the present case can also be applied to a 3D stereoscopic display device. In the previously published literature, a holographic image display device similar to the optical calibration module device, in which the holographic image of the optical calibration module device is imaged by a certain observer On the pupil of the eye. Such a display device has its exit pupil that will be placed against the pupil of an observer's eye and serve as a viewer window for reference. The last optical component in the display device can be seen in the direction of travel of the light and placed in front of the viewer for use as a screen. At this point we assume that this screen is a focusing optic. If the viewer window is aligned with the pupil of the eye in a holographic image display device, the observer will be able to see the recombination appearance of an object in a recombination map set and expand between the viewer window and the screen. Delay. However, if the observer moves against the edge or along the optical axis of the display device, the 200825455 viewer window will no longer be consistent with the viewer's eye pupil. This will result in an afterimage of the reorganized look and will only be partially visible or completely invisible. In order to avoid the aforementioned recombination appearance afterimages as the observer moves in the lateral direction by the previously proposed document or method, we will need a position detection system to detect the position of the observer's eyes. With the help of a tracking unit, the observer window can be tracked to the observer's eyes if the observer moves to another location. The observer window is also tracked from the side in the viewer plane. A lot of well-known literature has been published before this issue. For example, the patent document DE 10 2005 023 743.6, which is hereby incorporated by reference, describes a possible method for chasing the viewer window. With this document, the viewer window can be tracked by the aid of a refractive element located behind the light modulating module device and can be seen in the direction in which the light is directed. SUMMARY OF THE INVENTION However, such an arrangement arrangement is accompanied by a disadvantage in that since the tracking element is arranged between the optical calibration module device and the screen, and the image displayed on the screen is tilted, the image will be It will be distorted as the position of the observer changes. This will also cause the image on the screen to be skewed and skewed, and the reconstructed image will not be displayed. However, tracking the viewer window along the optical axis of the display device, i.e., along the screen or away from the screen, requires a different approach than lateral tracking. We must make sure that the observer window is actually moving in the direction of the optical axis, because otherwise the restructured appearance will appear as an afterimage in 200825455. In addition, the image of the light modulating module device must be imaged to the screen in the same manner forever and without any change, regardless of the distance between the viewer and the screen. This means that the image of the optical calibration module is similar to the position a given to an observer on the screen. It must be assigned to the position b of an observer on the screen, and the exit pupil must be displayed. A method that can be used for both lateral and axial tracking is described in detail in Japanese Patent Application No. 09068674, which also includes detailed illustrations. In this document, an electronic holographic image display for three-dimensional appearance display by means of two spatial light calibration modules is described in detail, which describes a light projection for adjusting the module from the light. A tilted mirror element to the observer's eye. Each optical calibration module with a corresponding holographic image will be expanded for the viewer's eye. The three-dimensional appearance is recombined in the area near or above the tilted mirror element. Any observer movement is detected by a position detection system and the tilted mirror element also rotates according to its horizontal or vertical axis to follow the new position of the viewer's eye. At the same time, the three-dimensional appearance corresponding to the new observer position is corrected in the hologram image. In addition, there is lateral tracking of the light, and an axial tracking, that is, along an optical axis of the display, is detailed in the figure. By the new position of the observer's eye, the light is tracked in a direction that faces or deviates from the three-dimensional appearance. Such a tracking method is achieved by modifying the lateral distance between the two optical calibration modules. Therefore, the light can be expanded to a certain determined eye. With the position of an observer's eye, the new eye position can be detected by the position detection system, and the light adjustment modules are arranged in a lateral form of 200825455 relationship. Therefore, the light will be tracked along the optical axis, and the reconstructed appearance will therefore always be visible to the observer's eyes. If we use the above tracking method, the problem of the afterimage will no longer be a problem, because the appearance after reorganization is very small. In addition, by this method, the light will be refracted after being adjusted by the adjustment of the optical calibration module. This will cause the image to be distorted or tilted. Also, with the patent application number JP 09068674, there is no defamatory observer window for subsequent tracking, but the remaining visible areas are tracked. In the H step, the system_hole is not in contact with the pupil of the observer's eye, but it will fall between the observer's eye and the reorganization. h If we need a larger recombination appearance, the method proposed in this patent will not be applicable. ^ (4) In this case, the case has a tracking imaginary window, and the so-called method and device will be able to track the observer in the lateral direction and the axial direction early and conveniently. Windows. The project borrows the methods and skirts proposed in this case, and we can achieve the functions listed in the application items 1 and 11. According to the method proposed in the present case, it is a display device, in particular, as the observer in the application item 1 moves to another position image image display device to facilitate the window, and the detailed execution details are as follows. : In order to trace at least - a virtual observer is present in the - observation =, and at this time there is at least one system to detect in the observer plane:. #在—Location The measurement system is the eye position of the inspector and transmits the detected Kai = Bellow to a control unit.

Hunting by the display device proposed in this case and the mechanism described in the 11th application can achieve another purpose, especially in the 砚:〒 group t. The display device proposed by the present invention is mainly applied to a holographic image display device which is displayed on a tilting or three-dimensional appearance. The device includes at least one light source and at least one light modulating module device that can be used to calibrate the continuous incident light using the appearance to be recombined. 2 曙 2M55 In addition, this ~ shows the viewer's observer, 匕 expand one to exist in the presence of at least one view. Also, the position detection system of the observer's eye position has at least a system, that is, a screen and a track for tracking in a viewer window:::spector: observer plane - a virtual view This tracking unit will be included in this display device. And can be seen in the position between the light source and the light adjustment module device, when the observer moves to another or axially, to 曰", "as a virtual observer window There will be any changes in the lateral direction and /. The image of the light adjustment module device on the screen is not optimal by the mechanism described in the strong document proposed in this case: Erji and the first application The observer of the special observer is arbitrarily arranged. The two-dimensional disc with at least one residual image is the observer plane. It can be used for lateral direction by means of no The image of the memorial and the axis school module is not different. In the case of the light, the image is displayed without tilting, twisting or tilting. The group will be seen, and the 蕤.

Group device ^= system, the special advantage is seen in s, is "turn 11 and stable m The help of the static filter optical system of the line is also in the beginning, and because of this, the image of the module device will not be distorted or tilted. The biggest advantage of the specific example proposed in this case is that The observer window we provide will be larger than the pupil size of the observer's eye, where the eye pupil is mainly used to filter the Fourier spectrum. As a result, the Fourier spectrum will be filtered out and the display device design will also It has become more 疋 sturdy. In order to avoid the continuous occurrence of the Fourier spectrum, we can use apodisation as a special frequency filter. The most common example so far has been published. Patent document DE 10 2006 030 535.3, which also allows the method proposed by the user to avoid the occurrence of periodic cycles. Another advantage is that the tracking unit provides an additional shirting system to enable a certain luminous beam. The aberration is corrected in the optical path.

The pupil will be flat: an observer Windows. I, 200825455 To see a restructured look, we must be able to make the pupil of the eye coincide with the virtual observer window. Otherwise, the reorganized appearance will be accompanied by an afterimage that is not expected. This is why we must have the virtual observer window closely follow the observer's eyes when the observer's position changes. A display device, particularly a display device for reorganization of the appearance, will be provided for tracking of the viewer window. The observer will therefore also be tracked laterally, i.e., to the right angle of the optical axis 1 of the display device, and/or axially, i.e., along the axis. A display device designed in accordance with the criteria described above is shown in Fig. 1. The display device comprises at least one light source 2, a tracking unit 3 for tracking the viewer window 4, an optical system 5, and an optical element 6 for use as a screen. The tracking unit 3 therein will be arranged behind the light source 2 and can be seen in the direction in which the light travels, and also includes at least two optical components (but not shown in this figure and other subsequent embodiments). ). In order to be able to track the viewer window 4 in the lateral direction in an observer plane 7, the tracking unit 3 may comprise a refractive element, such as an ammeter, so as to be able to image the element on the refractive element with at least one optical image ( For example, a lens) is refracted by light. In order to be able to track the viewer window 4 also in the axial direction, along with this optical axis 1, the tracking unit 3 can comprise an optical element which can change its optical properties, in particular the focal length. Such an optical component can be, for example, a liquid lens. In addition, the tracking unit 3 will include at least one other optical image rendering element beside a liquid lens. If a view 13 200825455 sU4 must be arranged in both axial and lateral directions, then the tracking unit light and the refraction section and a liquid lens like the whole person learn the image rendering mechanism. The π Μισ 3 king-like shirt-like light adjustment module device δ will be located after::: single two, and can be from the tracking unit Λ & Λ * 8 will adjust the light on the repair The rite 3 will modify the direction of the light, or the optical path of the illuminating beam 4 will begin to be subjected to the tracking light f 2 before the light is changed and will fall in the viewer plane 7. Because the viewing window 4 has been traced before the light is in the light, it is difficult for us to see the reorganization of the appearance. Only the silk II I:, especially a three-dimensional appearance, can be arranged by the optical system tombs & the optical system 5 is arranged in the light adjustment module device 8 ^ after and can travel in the light Seen in the direction. =,. Light =, 5 contains at least one optical component, such as a photo-adjusting module device 8 that is projected onto the screen 6 by the system 5 prior to being placed in a two-dimensional outer casing. =, the hologram on the optical calibration module device 8 = FT will be produced while the optical calibration module device 8 is being imaged. This Fourier transform FT will be generated by the optical system 5 and is not shown in the figures of this specific embodiment. Then this rich leaf conversion FT will be imaged through the firefly | 6 : U formation - _ viewer window 4. $ Observers will be able to see the restructured look produced in Reorganized Book Set 9 through 14 200825455. The reorganized album set 9 will expand and expand between the viewer window 4 and the screen 6, and may extend beyond any distance after the screen 6. In addition, the display device also includes a position detection system i 用来 for detecting the position of the observer's eyes in the viewer plane 7. The position detection system 10 is connected to the tracking unit 3, so that the information for determining the position of the observer's eyes, that is, the information detected by the position detection system 1 将会, will be provided to the control unit AU. When the examiner changes its position, it activates and controls the tracking unit 3 so that the observer window 4 can be laterally tracked (four) in the axial direction) and/or axially (z-axis direction). #果 observed, there is only a lateral change in position so that the observer window 4 will only be displayed sideways, then there will be no change in the position of the observer plane 7 along the optical axis. If a certain position is made at the observer position, the lateral and axial changes are integrated or integrated, and the observer plane 7 is displayed along the optical axis 1.

With the method proposed in this case and the original; = ^ will not be traced after the light (four) dragon correction, but = is set to 8 i = chase before the correction is corrected in the 模组 模组 school module device 8 The help of the vertical unit 3 allows the optical system, system 5 or optical element located in the optical calibration module assembly (4) to be seen at 3:= in the light, and remains static without change. This means that in the tracking element, by the refracting element such as the Fourier transform FT, the generated Fourier transform FT will be similarly adjusted to form the I:, and in the observation The viewer's window where the eyes are located is in Guanlan; Shun; Fig. 2 also shows a side view of the viewer 4 in the observer plane 7 from the t = system and the direction of the command axis. At the position of the scrutinizer's axis ί, the observer window 4 is formed around the light as indicated by the dotted line in the figure. 2 = 7 axis direction movement, even if the position of the observer by the light source becomes not (five), so that the light will not fall at a correct angle with the previous one. I 8 ^, and will take a different angle. I double the ratio of 4 and ensure that the collected beam phase Z on the optical calibration module device 8 does not change. The calibration module device 8 will always emit light, without changing any brightness. The actual & It is not an absolutely necessary condition that the light adjustment module unit 8 of the light ? A A t 发射 will emit parallel. The image of the light source 2 is thus not visible. As previously explained in Fig. 1, the fascia device 8 is projected onto the fluorescing system by the optical system 5, and at this time the Fourier transform F is generated in the optical to the same time, Where the so-called Fourier transform FT will be projected to image the viewer plane 7 to form the viewer window 4, or when the viewer moves to the new viewer window 4'. From the previously published solutions and literature, the light calibration module device 8 on the screen will not be displayed or tilted when it is tracked in the viewer window 4. It is used to filter the holographic image of the holographic image of the J-ray spectrum, which is added to the tuned module of the optical calibration module. As shown in Figure 2, 16 200825455 will be as shown in Figure 3. Further explanation. Thus, by the specific embodiment proposed in the present case, when the observer moves laterally, such as in the X-axis direction or in the y-axis direction, the viewer window 4 can be easily and conveniently tracked with a minimum of components. . The illustration of the axial tracking of the observer window 4 is shown in Fig. 3 as the observer moves to another position. With the specific implementation example presented in this case, the observer window 4 is tracked in the direction of the z-axis in the coordinate system, that is, the optical axis 1. The viewer window 4 is also tracked in the axial direction before the optical calibration mode set 8 and is seen in the direction in which the light travels. To achieve axial tracking, tracking unit 3 includes an optical component having a variable or controllable focal length, and at least one optical component, similar to a lens or mirror. An optical component having a variable focal length includes a mirror like a liquid lens, a deformable mirror, or any similar component. The position detecting system 10 detects the position of the observer's eyes and transmits the position information to the control unit 11 to activate the tracking unit 3. Therefore, the focal length of the optical component will be corrected so that the desired tracking of the viewer window 4 will be adjustable along the optical axis 1. The light emitted by the light source 2 and falling on the tracking unit 3 is affected by the optical component having the variable focal length, and the image of the unit 3 is tracked on the optical calibration module device 8 at different convergence angles. The image-forming component is projected and imaged, and the light calibration module device 8 adjusts the correction light to form a reconstructed appearance. The light can also fall onto the light modulating module unit 8 with a diverging beam of light, but we must first ensure that the modulating module unit 8 is able to illuminate constantly and constantly. Then, the optical calibration module device 8 will project the image on the screen 6 by the optical system 5, and the image on the screen 6 will remain unchanged even if the observer moves axially. This image will neither tilt nor expand and will not decay. At the same time, the Fourier transform FT will be generated during the image presentation. In the initial optical path indicated by the thin line in the figure, it will be generated in the optical system 5 and the position of the Fourier transform FT will only be implied in Fig. 3. In order to track the observer window 4 moving to 4', the image of the light source 2 will be displayed along the optical axis 1 and the position of the Fourier transform will also move from FT to FT'. The new observer window 4' will be formed by the image of the Fourier transform FT'. The viewer plane will also be displayed along the optical axis 1 to 7'. Depending on the axial position of the observer, the viewer window 4 will therefore be tracked to the observer's eyes. The lateral and axial tracking methods of the two observer windows 4 described above illustrate a tracking method in which the image of the module device 8 is not tilted or enlarged on the screen 6 without being replaced. As shown in Fig. 3, during the axial tracking of the size of the viewer window 4, all changes are proportional to the distance between the viewer window 4 and the screen 6, that is, the size of the viewer window 4 depends. At this distance. In addition, the display device, particularly the display device for recombination of appearance, includes a spatial frequency filter 12 located in the plane of the Fourier plane to transmit a selected image to the hologram of the optical calibration module device 8. The periodic spacing of the image of the Fourier spectrum. The best example of a display device is a holographic image display device with a light modulating module device containing a holographic image, a spatial frequency filter, especially an aperture, because one dimension is added to the enamel. Or a two-dimensional holographic image (where the morpheme is arranged in a form of 18 200825455 ii] will be in a periodic continuation of the spectrum of the leaf. ^ ^ generated in order to suppress or eliminate this - Cycle =), with - only used to transmit the diffracted null = 疋 car father good choice. For example, Gang Λ Λ 手 手 愿 愿 愿 愿 愿 愿 愿 愿 愿 愿 以及 愿 愿 愿 愿 愿_ System 5 provides the empty two = face. * Fruit_Window Along the optical axis ^ direction 1, the problem is that the spatial frequency filter 12 must be in place, and the spatial frequency is set.

An extreme speed to track the observer's frequency == Another advantage of the frequency filter 12 is to reduce the relic of the relics to a diffraction-like image of the Tianli gradation to a certain observation 2; (4) The effect of the surrounding interference in the wave device 12 generally goes to: chimney to prevent any noise from being placed in the holographic image recombination = the optical mode calibration of the array structure is about to multiply an image. No; == Love 2: 19 200825455 The left and right eyes are provided to an observer. Also, we can use multiplex processing to provide services to multiple observers. Another possible way to filter out the Fourier spectrum is to use the advantages of eye pupils as a filtering mechanism. In particular, the advantage of the viewer window 4 is greater when it is larger than the pupil of the observer's eye. Fig. 4 shows a detailed description of the tracking unit 3 in the specific embodiment of the axial tracking mechanism of the observer window 4 proposed in the present case. The collective beam emitted by the source 2 will be formed by an optical system H-H' having a variable focal length, such as, for example, a liquid lens or a plurality of individual lenses, such that the optical calibration module device 8 The parallelism or convergence or divergence of the collected beams is emitted, and the light source 2 will thus be projected along the optical axis 1 to be imaged in multiple places. In any example, the primary plane H' will be projected onto the optical calibration module device 8 by an optical imaging element L. The main focus of this is that the illumination area of the light adjustment module unit 8 does not change, and the main planes and H' are not displayed. Refractive elements that are capable of performing lateral tracking of the observer window 4 may also be disposed in a section of the tracking unit arranged before the optical imaging element L, so that the light source 2 does not need to be tracked for lateral or axial direction. And follow the move. Another problem with the aberration of an optical system is that the residual illustration effect produced by it will seriously affect the image quality of the reconstructed appearance. If the optical system 5 is static and optimized by the optical calibration module device 8 on the screen 6, as described above, or in the optical calibration module device 8 and the screen 6 The section between the two does not change, then the light 20 200825455 withering module device 8 will never project the aberration on the screen 6. However, we must assume in advance the observer window 4 or 4, in the tracking of the private It will be affected by aberrations. Such aberrations are mainly spherical aberration, comet-like aberration, and astigmatic aberration. This type of aberration occurs absolutely in an independent relationship with the projection of the optical calibration device 8 to the screen 6. We cannot absolutely confirm the degree of freedom of the aberration for the screen 6 and the viewer windows 4 and 4 at the same time. Aberrations may also cause a change in the viewer's window 4 or 4', similar to enlargement, which may result in an afterimage of the image on screen 6, because the collective beam emitted by the portion of screen 6 will Blocked by the pupil of the eye. So we need to correct this kind of aberration. A good enough aberration correction method = is to completely remove the effect of suppressing afterimages. In the system, the aberration correction method of the light adjustment module device 8 in the system, such as the optical system and system 5 in the specific implementation example proposed in the present case, can be achieved by appropriately adjusting the illumination wave front. The purpose is that the illuminating wavefront is emitted by a light source, for example using a suitable optical system. The ΪίΪ optical system will be disposed in a single το 3 in the front image of the light modulating module device 8, and thus projected onto the tuned mode assembly 8. We can also configure this suitable optical system in the image of the light module module 8. For example, in the optical system 5, we must confirm that the optical calibration module 8 will be in any situation. Monochromatic illumination is performed with a constant brightness intensity. For example, the aberration in the viewer window 4 can be corrected appropriately. And the appearance of { will prevent the generation of afterimages. In this winter, the image quality of the reconstructed appearance is improved. 21 200825455 With the display device proposed in this case and = chasing: fruit - * to the exit pupil or observer: window ':: chasing pepper - (6) If necessary, when viewing: the direction of the curtain 6 is moved , will therefore face the glory 6 or deviate from Rong = illustration. The image of ... will also be vertical ===: in the chasing τγ window of the chasing brain display screen, such as the display, for example, is an electronic video game machine, used in the automotive industry ^ Mjf & Screens, monitors, and the movements of the viewers and the pupils of the eyes of the observers are all traceable to the field of application that can be applied for in this case. All of them are unprecedented::: The technology of dew, It is still not enough to implement the example according to the technical person of the scholastic technique: the application for the patent is proposed by the method. However, the scope of the above patents is attached. 〃々人保遵的专利范围, therefore, application 22 200825455 [Simple description of the diagram] The second frame is used to trace the display window of an observer window proposed by the observer.
