Better resolution, contrast and luminance have improved head-mounted virtual and augmented reality systems, giving airborne pilots and seagoing navigators a ‘true-to-life’ representation of the battle theater.HANK HOGAN, CONTRIBUTING EDITOR, [email protected]“Fight like you train and train like you fight” is a military maxim. To better do that, the military is turning to virtual, augmented and mixed reality. In virtual reality (VR), digital representations replace the real world, with a high-end example being immersive simulators with realistic sights, sounds and motion. In augmented reality (AR), projected data overlays what trainees see. Mixed reality (MR) combines the real and synthetic. When there are multiple projectors in a virtual reality simulation, they must have their output blended and warped to avoid artifacts where...Read full articleRelated content from Photonics MediaARTICLESDigital Age Sees New Demand for the Venerable ConoscopeAfter languishing for the first century of their existence, conoscopes have become essential to the production of consumer products in an increasing number of industries.

Similarly,...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookInfrared System Design: Understanding the Process: While equations and data pertaining to infrared system design abound,1 comparatively little has been written about the process.2 This article attempts to fill that void.Infrared system design is not, like some circuit design, a synthetic process.
