Each microlens has multiple pixels underneath it. Each pixel generates a ray that has a unique origin and angle when it comes out of a microlens.<ref name="f364"/>

+
+Two lenticular sheets perpendicular to each other can be used to emulate a microlens array.<ref>https://www.jsr.org/hs/index.php/path/article/download/5965/2712/39803</ref>
+
+The spatial resolution of a simultaneous light field display is proportional to the ratio of the microlens focal length to the distance of the display from the eye.<ref name="w353"/>
+
+===Douglas Lanman's Nvidia near eye display===
+[[Douglas Lanman]]'s NVIDIA research publication's display used two Sony [[ECX332A]] OLED microdisplays as the light sources.<ref name="w353"/>
+
+It used microlenses from a Fresnel Technologies #630 rectangular plano-convex microlens sheet.<ref name="w353"/> The microlenses had a focal length of 3.3 millimeters and lens width of 1.0 millimeters. The microlenses were oriented with the planar surface facing the viewer.<ref name="w353"/>
+
+It was demonstrated at [[SIGGRAPH 2013]].<ref name="k223">{{cite web | title=NVIDIA Research's near-eye light field display prototype eyes-on | website=Engadget | date=2013-07-27 | url=https://yewtu.be/watch?v=kcmD2s6E-LE | access-date=2024-07-09}}</ref>

+A copy of the project was made in about 2015 by Richard Assar, who used the same components as the original project.<ref name="b156">{{cite web | title=Near-Eye Lightfield Display Project | website=Richard Assar | date=2016-04-16 | url=https://yewtu.be/watch?v=HhIWeJxWQpk | access-date=2024-07-09}}</ref>
