Hogel

Hogel (wani hoto na kalmomin holographic da element ) wani ɓangare ne na hologram mai haske, musamman wanda kwamfuta ta samar . Ana ɗaukarsa ƙaramin abu mai haske na holographic ko HOE kuma tasirinsa gaba ɗaya ga na hologram na yau da kullun kawai cewa ƙudurin ya yi ƙasa kuma yana ɗauke da tsarin pixelated.  Jerin waɗannan abubuwan suna samar da cikakken hoton rikodin holographic, wanda yawanci ana nuna shi a cikin na'urar kallon kyauta ta 3D. 

Sabanin pixels 2D, hogels suna ɗauke da alkibla da ƙarfin haskoki masu haske daga fuskoki da yawa kuma a zahiri shine abin da ake kira micro-image a cikin kalmomin hoton plenoptic. Ana yin hogels na roba ta hanyar yanka biyu, yanke da da'ira ko kuma bin diddigin hasken polygonal/voxel/ray-casting. Bincike kan samar da ingantaccen tsari da matse hogels na iya ba da damar nunin holografi ya zama mai yawa.

Ana iya amfani da jerin hogels don sake gina filin haske ta hanyar fitar da haske ta hanyar jerin microlens ko ta hanyar hologram masu haske/watsa hotuna. Amfani da hogels yana kawar da iyakancewa akan adadi da girman pixels da kuma girman ruwan tabarau waɗanda suka ƙunshi jerin ruwan tabarau saboda holograms ba abubuwa bane na zahiri.  Bayanan da aka yi rikodin a cikin hogel suna ta hanyar hasken abu.

Mark Lucente ne ya ƙirƙiro kalmar "hogel" wanda ya fara amfani da ita a cikin takardar digirin digirgir ta MIT ta shekarar 1994. 

Misalai na baya-bayan nan sun haɗa da takarda da aka gabatar a taron shekara-shekara na SMPTE na 2 a kan Stereoscopic 3D don Media da Nishaɗi mai taken "The First 20 Years of Holographic Video - and the Next 20",  ko kuma a cikin waɗannan surori na littafin kwanan nan: "Electronic Holography - 20 Years of Interactive Spatial Imaging" a cikin Handbook of Visual Display Technology [2] , da kuma "Computational Display Holograph" a cikin Holographia.
