International Conference on Communication, Media, Technology and Design 24 - 26 April 2014, Istanbul – Turkey Classification of Holograms and Types of Hologram Used in Holographic Art Vildan Işık Department of Industrial Design, Faculty of Engineering and Architecture, Meliksah UniversityTalas/Kayseri, Turkey [email protected] ABSTRACT Holography is a modern imaging technique which was created by the research and applications of numerous physicists, chemists, mathematicians and engineers, and which is still being continue to develop. With this technique, recording and storage of the light and sound and re-creation of them at the desired time and space is intended. Mainly used in scientific and technological research and applications, holography, also began to be used increasingly in the field of art in many countries, by the time many artists had discovered the artistic potential of this technique in the 1960s. Holography is a technique that include many hologram types. Some of these types could be used in the holographic art, however each hologram type is not appropriate for artistic use. In order to understand which of them could be used in art, firstly classification of this technique as well as the types should be known. In this study, holograms are classified, and hologram types used in the holographic art,and holographic art terms are examined. Keywords: Holography, hologram, holographic art, classification of holograms, types of hologram, terminology of holographic art, INTRODUCTION In 1947, Hungarian scientist Dennis Gabor who’s an electrical engineer and physicist is the first who find the technique and gives it the name of Holography ( Hecth, 2010). With this technique, all the features of the waves; wave intensity (wave height ); wave color (wavelength) and wave direction (wave vibration angle) are recorded, stored and reconstructed (Onural, 2008). Previously, holography was a technique which is used only in laboratories, afterwards it increasinly has began to be used in more and more areas. Artistic potential of holography was discovered by a small group towards the end of the 1960s. Holography has a process which’s similar to the history of photography in terms of technical improvements, market demand and artistic acceptance. The artistic acceptance of the holography and the evaluation of it as a separate art form is based on the post-1980s (Johnston, 2006). Holograms are produced by different techniques in holography, so that there are many different kinds of holograms. Knowledge of the classification of holography and the used varieties in understanding and evaluating the holographic art will contribute significantly to the preference of which type of hologram will be preferred. Therefore, in the study firstly the classification of holograms described and afterwards the hologram types which are frequently used in the holographic art is explicated (Işık, 2014). Classification Of Holograms Holograms can be classified under the following headings (Işık, 2012): Use and Study Area.There are many holograms which are used in many areas and for different purposes such as optics, electronics, medicine, IT, architecture, museology, art, culture, industry, military and security. These are classified according to the use and examination purposes under the headings like medical holograms, art holograms and security holograms etc. Optik and Electonic Elements.Different kinds of holograms arise according to the holographic optical elements (HOE) such as lenses, mirrors, filters, prisms and etc. and holographic electronic elements (HEE) such as electrons, crystal displays, cameras, computers, etc.. which are used in hologram recording and re-construction. Holographic Object.Holographic object can refer to an object which is dead or alive, with or without motion as well as it can refer to the sound frequency, microscopic organisms, electrons which are so small to be seen visibly and subatomic particles. Also sometimes a hologram may be the object of another hologram (fig.1). Depending on the nature of the holographic object different hologram varieties are emerging. 35 International Conference on Commu unication, Me edia, Technolo ogy and Desig gn bul – Turkey 24 - 26 Aprril 2014, Istanb Fiig. 1.

There T could be e different holo ogram types su uch as ection, transmission, single beam, b off-axis,, on-axis. refle ational Conference on Com mmunication, Media, Techn nology and Design Interna 24 - 26 April 2014, Isttanbul – Turkey Copy and Mu ultiplication.C Copying and re econstruction of holograms with various analog a or digittal methods is s possible (fig.1).These methods m are ge enerally groupe ed under the fo ollowing headings: Broken B Hologrram. A holographic plate/film m preserves all of the informa ation belonging g to the whole in all of its pie eces even if it is broken. Each of the brroken pieces may m be used as s a master holo ogram. This feature is not av vailable in everry type of hologram. Tran nsmission-H1 holograms h are that like holog grams. Hologram's H Ho ologram. Makin ng a hologram to be the obje ect of another hologram h and producing a ne ew hologram is s possible. These T could be e defined as copy hologram or H2, H3 etc c. White light transmission, t rrainbow and multi-channel m h holograms are a of this type e. Developing D P Phase.Some h holograms has been going th hrough a bathrroom process in the dark roo om after the record. r In this t process which w the reco orded image is stabilized, tto increase the e transparency y and gloss of o the hologram also a bleaching b operration is applie ed with chemicals (fig.2). Thiis type hologra am which become transparen nt by bleaching g is called phase p hologram m. Artists often uses bleache ed phase holog grams to show the 'back' of th he hologram to o the viewer. Color.Different kinds of hollogram arises according to the usage of red, blue, gre een laser beam ms individually y or by a combination c (ffig.3,4). These are different hologram h types s such as achro omatic, true co olor, pseudo co olorand, multi color. Illumination. I n the method they’re record ded, hologram ms are displaye ed in differentt ways and are sorted Depending on accordingly a (fig.3,4). Some holograms h are visible with la aser, some in a special light source, and so ome in an ordinary light source s or dayllight. For exam mple, transmission-H1 holograms are visib ble with laser, whereas holog grams such as rainbow, solar s embossed hologram can be seen in ordinary light. Construction Stages.To de efine the holog grams accordin ng to their con nstruction stag ges H1 and H2 2 symbols are used. In some s types, for f example in n sandwich hollograms H3, H H4 symbols arre also used (T Tornare, 2007 7). H1; is a single step hologram whic ch can be used d as a master hologram. h This s is the direct recording r of th he laser beam as a a one step operation from f the objec ct. The symboll of H2 is used d to define a co opy hologram which is the h hologram of a hologram or a two step hologram (MIT T, 2001). Dimensions.D D Dimensions is pointing to the e hologram siz ze as well as to o x, y, z plane es (fig.4). It is possible to cla assify the holograms acc cording to theirr size in three different d ways:: n Holograms. Thick T hologram points to the volume and thinhologram po oints to the plane. Thick and Thin Small S and Larg ge-Scale Holog grams. Size de efinition, an ed dge with new techniques, t it u usually ranges from 60 cm to large is called c large-sc cale hologram..
