Value Engineering 0引言全息技术是物理学中一重要发现，越来越多的应用于各个行业。

伴随着CCD 技术和计算机技术的发展，全息技术也得到一次质的飞跃，从传统光学全息到数字全息。

传统光学全息将物光和参考光干涉得到全息照片来记录光的振幅和相位信息，而数字全息则用CCD 记录物光和参考光的干涉，形成数字全息图，再通过计算机图像处理技术处理全息图。

因此，影响数字全息技术发展有两个重要方面：CCD 技术和计算机图像处理技术。

本文将从计算机应用方面阐述图像处理技术在全息中的应用。

1图像处理技术图像是现代社会人们获取信息的一个主要手段。

人们用各种观测系统以不同的形式和手段获得图像，以拓展其认识的范围。

图像以各种形式出现，可视的、不可视的，抽象的、实际的，计算机可以处理的和不适合计算机处理的。

但究其本质来说，图像主要分为两大类：一类是模拟图像，包括光学图像、照相图像、电视图像等。

它的处理速度快，但精度和灵活性差。

另一类是数字图像。

它是将连续的模拟图像离散化后处理变成为计算机能够辨识的点阵图像。

从数字上看，数字图像就是被量化的二维采样数组。

它是计算机技术发展的产物，具有精度高、处理方便和重复性好等特点。

图像处理就是将图像转化为一个数字矩阵存放在计算机中，并采用一定的算法对其进行处理。

图像处理的基础是数学，最主要任务就是各种算法的设计和实现。

目前，图像处理技术已经在很多方面有着广泛的应用。

如通讯技术、遥感技术、生物医学、工业生产、计算机科学等等。

根据应用领域的不同要求，可以将图像处理技术划分为许多分支，其中比较重要的分支有：①图像数字化：通过采样和量化将模拟图像变成便于计算机处理的数字形式。

③图像的增强和复原：主要目的是增强图像中的有用信息，削弱干扰和噪声，使图像清晰或将转化为更适合分析的形式。

③图像编码：在满足一定的保真条件下，对图像进行编码处理，达到压缩图像信息量，简化图像的目的。

以便于存储和传输。

关于全息技术的英语作文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 lightand 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 laserhologram 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.。

全息投影手环的作文英语英文：As a tech enthusiast, I have always been fascinated by the idea of holographic technology. And when I first got my hands on a holographic projection bracelet, I wasabsolutely blown away by its capabilities. The holographic projection bracelet, or "hologram wristband" as some people call it, is a revolutionary piece of technology that hasthe potential to change the way we interact with the world around us.One of the most amazing things about the holographic projection bracelet is its ability to project 3D images and videos right onto the user's wrist. This means that you can literally have a holographic display right in front of your eyes, without the need for any bulky screens or devices. Imagine being able to watch a holographic movie or play a holographic game, all from the comfort of your own wrist.It's like something straight out of a science fiction movie!But the holographic projection bracelet isn't just about entertainment. It also has practical applicationsthat can make our lives easier and more convenient. For example, imagine being able to project a virtual keyboard onto your wrist, allowing you to type and send messages without needing a physical keyboard or touchscreen. Or imagine being able to project a map or directions right onto your wrist, making it easier to navigate and find your way around.Of course, the holographic projection bracelet is still in its early stages, and there are some limitations to its capabilities. For example, the quality of the holographic images and videos is not yet as high as traditional displays, and the battery life of the bracelet can be quite limited. However, as technology continues to advance, these limitations are likely to be overcome, and we may soon see holographic projection bracelets becoming a common and indispensable part of our daily lives.In conclusion, the holographic projection bracelet isan incredibly exciting piece of technology that has the potential to revolutionize the way we interact with the world around us. Its ability to project 3D images andvideos right onto the user's wrist is truly mind-blowing, and its practical applications are endless.
