A high speed CRT requires bright phosphors with very fast decay time. Such a phosphor has recently become available and is used in a custom CRT which is driven by high speed electronics designed at Cambridge. The shutter is another custom component and is manufactured by Thorn EMI, with driving electronics again designed at Cambridge. It utilises a modern ferroelectric liquid crystal, which has a switching speed below 100 microseconds. A true 3D TV is useful in any situation where depth perception is vital.
Remote manipulation is perhaps the most obvious example.
Various scientific and medical visualisation tasks will benefit from true 3D viewing. Organic chemists already need to use 3D to visualise the complex molecules that control the life processes. Computer aided design of complex three-dimensional structures would also benefit from the addition of a true 3D display. The entertainment market is rapidly expanding. We are still some years away from seeing 3D TV sets in our homes, but it may not be long before true 3D displays appear in video games.
