Chromatra’s unique Gemini™ 2-channel technology
Two filter wheels are rotated in sync in front of and behind the PVS-14.
The light then enters the PVS-14 where it is amplified in the normal manner.
Because the two filter wheels are synchronized, the two channels of color information are displayed to the user who is looking through the rear filter wheel at the PVS-14’s phosphor screen.
The human brain is able to take the color information encoded in this manner and cause the user to perceive a near-true color image.
