Digital Projection Close Quarters Sight (DP-CQS)

Non-magnified reflex sights have been and continue to be an essential tool for rapid target acquisition and engagement in close-to-medium quarters engagements on the battlefield. Various reflex-style sights have been developed over the years, including prism-based (etched reticle), red-dot, or holographic, each with their own strengths and weaknesses. While the most basic implementation of a reflex sight, the red-dot sight (RDS), is simple, low power, and reliable, all implementations require mechanisms and adjusters to set and maintain boresight.  These mechanisms require careful material selection, design, and assembly to maintain zero when exposed to shock and temperature. Furthermore, traditional reflex sights are limited in terms of options for varying shape/color reticles. Prism and holographic reflex sights by nature of their design have fixed reticle shape (and in the case of holographic, color) and while there are “red-dot” sights on the market that change color and/or reticle shape, they are typically limited to poorly constructed commercial offerings as they present problems with color shift and/or boresight stability when switching reticle patterns. An all-digital solution can modernize reflex sight technology and address many of these issues. New solutions exist to improve  boresight stability while offering multiple reticle shapes, and can also allow for additional benefits such as ballistics compensation, drop & wind hold indicators, or display of other relevant data (battery life, cant, range from an external LRF, etc.), all while preserving the ability of magnifiers to be used behind the reflex sight to extend range capability.
