| 1. | The signal beam can be recreated by illuminating the medium with a beam identical to the original reference beam
通过用和原始参考光相同的光束来照亮感光介质可以还原信号光。 |
| 2. | This “ signal beam ” then meets a separate reference beam , and where the two beams intersect they create an interference pattern in a light - sensitive medium
然后，信号光会和另一独立的参考光相遇，当两个光束相交时，它们会在感光介质中制造一个干涉图样。 |
| 3. | The clear images of objects are reconstructed by using frequency domain algorithm . ( 3 ) in experiment , different reconstruction images are obtained by using different fibers
( 3 )在实验中使用不同的光纤传输物体照明光和参考光，拍摄全息图并通过再现得到了不同效果的再现像。 |
| 4. | The reference beam comes from the object wave itself and image of the object is formed by a lens on the plane of the holographic plate , therefore the hologram is named self reference image hologram
用透镜将物体的像成在记录干板平面附近，参考光来自物光本身，因此称之为自参考像全息图。 |
| 5. | This chapter introduces one technique which based on encrypting the access of storage data , this can be done by coding the phase of reference beams by use of orthogonal - phase - code
介绍了一种基于对接入加密数据通道进行加密的方法，即对参考光的相位进行正交相位编码； 4 .双随机相位编码加密光存储。 |
| 6. | The major drawback of the method is the low spatial resolution of ccd arrays , because of which , the angle between the reference and the object waves must be limited to a few degrees
目前， ccd低的分辨率是数字重现技术的最大的制约因素。 ccd低的分辨率限制了物光和参考光之间地夹角，使得实验精度要求很高。 |
| 7. | Crucially , hundreds of such patterns , and hence hundreds of pages of data , can be superimposed within a given volume of holographic material , provided each is recorded at a slightly different angle ( see diagram )
然后，信号光会和另一独立的参考光相遇，当两个光束相交时，它们会在感光介质中制造一个干涉图样。 |
| 8. | The basic principle of digital holography is that , by replacing the ordinary films with ccd , the hologram of the object and the reference waves can be obtained and reconstructed by numerical computing
数字全息的基本原理是用光敏电子元件(如ccd )代替普通照相记录介质，获取物体和参考光的干涉全息图，然后用数字计算方式再现。 |
| 9. | I simulate the whole circuit by hspice and get the result that the output signal voltage is linear with light - intensity and the light dynamic range reaches to 9 . 5 w / square meters ( room illumination is about 0 . 1 w / square meters )
对整个光电转换电路,采样输出电路的仿真得到输出的电压信号与光强基本成线性关系。可响应的最高光强是9 . 5瓦/平方米(室内的参考光强为0 . 1瓦/平方米) 。 |
| 10. | We put forward a scheme that the oil contamination sensor with reference route is applied in this system according to the measuring difficult on incidence light and the influences from oil color and transparency of the oil contamination sensor with single route
本文针对传统的单光路结构的入射光强测定困难、油液颜色以及透光率影响测量结果等问题，提出了利用带参考光路的监测方法来解决。 |
