但是为固定的物体造一个全息图像就够难的了，做个全息显示器就难上加难。
But producing a fixed hologram of a static object is tricky enough; making a holographic display, or something that functions like one, is even more difficult.
这个装置目前只能显示一种颜色。但是，科学家们之前已经开发出了刷新率更高的彩色全息显示器。
The system currently works in just one colour. However, the scientists have previously developed colour holographic displays that refresh at a faster rate.
Holocube公司并没有透露这类产品何时才能上市，不过他们表示正在开发一种屏幕尺寸为42寸的全息立体显示器。
A timetable for its release wasn't given, but Holocube is developing a 42-inch non-touch version of its holographic display.
这种轻触型工具播放的近距离图像是在0.4英寸的微小型显示器上反射的激光形成的，使用全息摄影术以保持图画尽管在投影尖角上依然聚焦。
The Light Touch casts a big image from up close by bouncing lasers off a 0.4-inch microdisplay, using techniques from holography to keep the picture in focus despite the sharp projection angle.
他认为，当前方案中用于照明全息图的棱镜被固定在覆盖金属的材料下方或后方，当制作更大显示器时会成为负担。
The prisms used to illuminate the holograms, which in the current scheme are mounted beneath or behind the metal-coated material, could easily become cumbersome in much larger displays, he contends.
用重铬酸盐明胶介质记录了用于飞机平视显示器的平面离轴反射全息目视显示元件。
Off-axial reflection holographic visual display elements which records in dichromated gelatin (DCG) deposited on planar substrate of glass has been developed for pilot head-up display (HUD).
