The three dimensional imaging holography has many application in physics and otherrnscience ,as a result many text describe the constructing and reconstructing techniquesrnof different types of holograms .However; these descriptions are hard to understandrneasily and apply ,especially in our country Ethiopia .Since there are no trends actuallyrndone on the applications of holography , strong researches are not yet carried outrn,and the subject not included in the curriculum for education in high schools andrnin university ,Hence in this project work I am interested to make it clear so thatrneveryone can understand and use it effectively .rnIn this project work ,it tries to cover the basic theories,facts and principles ofrnthe physics of holography ,in addition to this the theoretical and the experimentalrnbackgrounds to make an advanced transmission hologram , how to reconstruct it andrnmeasure the image distance and height.Moreover; the lateral magnification elaboratedrnqualitatively and quantitatively by reconstructing the transmission hologram , so asrnone can understand how we can able to determine the unknown wavelength of laserrnused in reconstruct the hologram but not in constructing the hologram.rnFinally holography can be put to a variety of uses other than recording images. sornthe knowledge of holography is very important to our country to overcome problemsrnin our day to day activities like holographic data storage technique that can storernand others, then at the end of this project work i am tried to included some of thernapplications of holography
