Chromatra’s unique Gemini™  2-channel technology

1.

Two filter wheels are rotated in sync in front of and behind the PVS-14. The front filter wheel uses two unique [“special”] filters. The color information in the light entering the CVA is thus sequentially encoded into two channels of information.

2.

The light then enters the PVS-14 where it is amplified in the normal manner. The amplified sequential images are then displayed on the PVS-14’s phosphor screen.

3.

The emission spectra of both the green and white phosphors used in the PVS-14’s have a green-blue component and a red/orange component. 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, alternately in blue/green, and then red/orange.

4.

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.
