由日本Chiba大学工程部和NKG绝缘体材料公司组成的一个研究组,开发成一种试验性全息摄影系统。该系统可从用X-CT拍摄到的平面图像中,应用数据构成实时全息图。这种试验系统应用BSO(铋硅氧化物)晶体代替了常规的负片。应用这种新系统,在显像管上的断层图像用棱镜和反射镜导向BSO晶体,然后采用氦氖激光使BSO元件记忆图像。而另一激光作用于元件的后面,把图像投射于全息片上。先把全息片向后移动,相继在显像管上录印图像,即能构成立体的全息图。BSO晶 A research group consisting of the Engineering Department at Chiba University in Japan and NKG Insulator Materials developed a pilot holographic system. The system uses X-CT images taken from the plane, the application of data to form a real-time hologram. This test system uses BSO (bismuth silicon oxide) crystals instead of conventional negatives. Using this new system, the tomographic images on the tube were directed to BSO crystals using prisms and mirrors, and the BSO element was then imaged using a He-Ne laser. While the other laser acts behind the component to project the image onto the hologram. First move the hologram backwards, one after another in the picture tube to print the image, which can form a three-dimensional hologram. BSO crystal
