Default Sampling



If light is treated as a signal and the eye and brain of a human is a sensor
and interpreter of the signal.

From sampling theory (Nyquist and Shannon) to represent a signal exactly as
it is - its necessary to at least sample at twice the frequency (usually
higher than this)

Although it *is* possible to break with this traditional thought!






Is this a valid question??


How fast does the human eye/brain system sample light??


Regards

Setanta

The human eye cannot exceed the Nyquist limit, but the eye is connected to a
brain which can imagine all kinds of things stimulated through the eye.


1/30th of a second is about the limit of the eye/brain's ability to image.
Longer is better.
