US 8,573,977 B2 · Generating images for detection by night vision devices

Abstract

Methods, apparatuses, and flight simulators are disclosed to present infrared images detectable by night vision devices. A video signal may be received. The video signal may be configured to generate a viewable image substantially within a human visible spectrum. The video signal may include one or more of a red component, a green component, and a blue component. The video signal also may be configured to generate one or more infrared images. The one or more infrared images may be substantially outside the human visible spectrum and may have an infrared component detectable by a night vision device. In response to the video signal, the red and green components may be separately modulated to generate red and green portions of the viewable image. The blue component and the infrared component may be collectively modulated to generate a blue portion of the viewable image and the one or more infrared images.
