T3D visual acuity improved by binocular vision

["Edward Gosfield III, MD" <egosfield@xxxxxxx>]

Jim C. notes the possibility that removal of random fluctuations in photons
and neural noise may be responsible for binocular vision increasing visual
acuity. (this would then be a 'special case' of the "anomalous disparities"
John B. posits.

Jim's explanation is well accepted in astronomy, and supported by published
research (which i cannot cite).  Detection of dimmer stellar magnitudes is
improved when using binoculars over single eye, and when using a binocular
eyepiece hooked up to a single telescope.

In addition, detection of filamentary, nebular, and other 'extended' detail
is improved in the same manner. 
 
1)more photons are collected
2) "counting statistics"  (as we say in nuclear medicine) are improved,
with reduction of noise and consequent improvement of signal to noise ratio
as well as improvement of absolute detection limits,

 i believe some of the effect on 'extended feature' detection is considered
the result of cognitive processing (ie, cortical processing) not just
improvement in sensory input characteristics.


"More light"....Goethe's last words (he did physics experiments on light, too)
