Nyquist frequency of human eye.

AI Thread Summary
The Nyquist frequency for the human eye is not clearly defined, as the eye operates in an analog manner. Refresh rates for monitors should be high enough to prevent the perception of flicker, with recommendations varying between 10-120Hz. The eye can detect individual images at high speeds, but the effective refresh rate also depends on the content displayed. High-quality TVs often operate at 240fps, yet most video content typically ranges from 14 to 60 FPS. The term "Flicker Fusion Frequency" may be more appropriate for discussing this phenomenon.

I'm designing a monitor and I've been getting various answers to this, seems to really depend. I've gotten everything from 10-120Hz.

There's is not really a Nyquist for the eye, the eye is "analog" - for monitors, and televisions you are looking for the refresh rate that the eye will not perceive the flicker - or strobbing of a digital image. The eye can pick up individual images at pretty high speed. That will depend on what will be on the monitor - High quality TV are at 240fps - but then it will still depend on the content and does it introduce distortion. Keep in mind that most video content is between 14 and 60 FPS

A better name for this is Flicker Fusion Frequency...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
