Dear Dennis,
I'm very happy when Iget your letter.
Don't be dismayed.Here are some advices.
First you said your new school is very beautiful.I think a nice environment is good for you to make friend.You can make a self-introduction so that other people can know you well.You also actively and say "hello to others.
Then don't worry about your grades.Your teachers are kind for you.You can ask the teacher for help when you had problems.Don't be shy.That's nothing.Why don't you ask your classmate for help?It can not only improve your grades but also let you get on well with your classmate.
In the end,I hope you can make many friends.And scores more and more good

Keep healthy and happy,you'll have a good time.
Please write to me soon.

只要那个犯了错的孩子放回10美圆,他就会得到一个小太阳,弥补了错误,他就不会再是一个小偷而是和别的孩子一样拥有美好的品行和心灵.我觉得小太阳的内涵可能是孩子的美好的心灵.也不知道对不对,有一段时间没做这样的题了.后面那个题...我就算了吧,我还是有自知之明的.

A holographic technology Introduction
Holographic technology is 1948 British scientist Dennis Jiabo (Dennis Gabor) to improve the electron microscope imaging quality reproduction made by the theory of wave front, and has received a Nobel Prize. However, since the lack of pure light can interfere with each other, the poor quality of the hologram. Until twelve years later in 1960, the advent of lasers, the University of Michigan and Zhu Ai Meidi Leese Rhys Youpeinike made into a first holographic photos, holographic technology have a vigorous and rapid development.
In 1948, Jiabo to improve the resolution of electron microscopy, in Prague the "x-ray microscope," Zernike phase contrast, inspired by the principle, we propose a recording object wave with wave amplitude and phase of the method, and the experimental confirmed this idea. To further confirm the principle, he has used the electron wave and visible verified, and has been confirmed in the visible, and into the first hologram 1. From then until the late 20th century, 5O, holograms are used mercury lamp as the light source, and the reference light and the object light of the shaft being coaxial coaxial holographic hologram. It 4-1 order diffracted waves are inseparable, it is holography infancy. During this period there is a hologram two serious problems, one is a reproduction of the original image and conjugated as inseparable; another source of coherence is bad, so in the past 10 years, holography has been slow.
Off-axis holography there is generated after the laser recording laser reproducing laser holography, characterized by reproduction of the object image obtained with the illumination light is separated, easy to observe.
The emergence of the laser in 1960, provides a high degree of coherence light. 1962, U.S. scientists Leith (Leith) and upa Courtenay · Alex (Upatnieks) to the carrier frequency of communication theory concept to the airspace, the proposed off-axis holography, the reference is to use off-axis light and matter a hologram interference of light, and then irradiated with light using off-axis hologram of the reference, the hologram produces three spatially separated from each other diffracted components, wherein a copy of the original object light. Thus, the coaxial two problems declared resolved holograms, laser recording generated laser hologram reproduction. So that holography sleeping after a decade to get a new life and entered a very active phase. Since then, they have appeared in a variety of holographic methods, such as large depth of field holographic radiography, laser recording and reproducing color laser holographic photographic method and so on.
White is the use of white light holography holograms produced by laser or white light observation reproduction, which is the highest stage of holography, although many people still do some preliminary work, but no breakthrough. The highly coherent laser, the hologram recording process of the various components, the light source and the recording medium is strictly maintained the same relative position. It also gives practical use of holographic technology has brought inconvenience. Thus, scientists have come back to continue to explore the white white reproduction of hologram recording possibilities. It will make the final out of a shock holography dark laboratory bench into the broader practical fields.
