In the proposed time-spatial multiplexing naked-eye 3D display system, the light illuminating on LCD should be diverted to the designated viewing zones, which can be realized by importing an LCE between the light source and LCD.
In the naked-eye 3D display, a series of light emitting diodes (LEDs) are used as the light source for the advantages of energy efficiency, long service life, and low heat dissipation.
Famous as a wide and easy pair in binoculars, Alpha Librae's toughness to resolve naked-eye may be surprising--until you imagine Mizar and Alcor three times closer together, and with a greater magnitude difference!
This lovely naked-eye optical double adds to the overall fascination of the district around Antares and the head of Scorpius, as shown at left.
Nowhere are so many naked-eye
stars packed into such a small area of sky--eight stars brighter than magnitude 5.5 within a 1 [degrees] circle.
Equally memorable was stepping into our host's observatory dome and seeing the great Auriga Messier clusters become easy naked-eye
glows as the dome shielded the rest of the sky from sight.
It's often assumed that the naked-eye
limiting magnitude under good conditions is 6.5--though this is conservative.
Even accepting the eye's limited field of view, October evenings are not a bad time to see the most naked-eye stars; spring evenings have far fewer.
On the very clearest, darkest nights, I've seen parts of Cygnus pebbled, beaded, and curdled with naked-eye stars.
At what magnitude do naked-eye
stars and planets show their colors best to you?
And the one I want to talk about now involves 4.5-magnitude Nu ([nu]) Andromedae, the naked-eye star closest to M31.
Many naked-eye observers, especially young ones, have split the double star [Epsilon.sup.1,2] ([[epsilon].sup.1,2]) Lyrae, whose 5.1- and 6.0-magnitude components are separated by about 3 1/2'.
