Just How Do Holographic Sights Work?

SEnuke: Ready for action

With a mainstream optical scope, a shooter should have his eye aligned with the scope so that you can spot the reticle over the target. If the shooter's head is not properly aligned, the scope's reticle is not going to the same location on the target as the weapon.

Holographic weapons views have become increasingly popular with photographers, because they give the shooter the ability to quickly lock in o-n target, even though the shooter's head position is not aligned with the view.

With a mainstream optical scope, a shooter will need to have his attention aligned with the scope so that you can position the reticle over the goal. If the shooter's head is not perfectly aligned, the scope's reticle isn't pointing to the same location on the target as the weapon.

With a holographic (~~'~ holo ~'~~) picture, the reticle is always on the spot on the mark where the gun is directed. Move the gun left or right, and the reticle goes too, but remains on-the point-of aim.

How is this possible?

Unlike the view you see through a main-stream scope, what you're seeing through a holographic picture is not real. It's a reconstruction of the view. What's more, the reticle which you see is not really within the sight, but is a projection of a reticle image.

Before you start scratching your head, think of watching a movie. The film camera has recorded the the light reflected in the objects in a world onto film. When the film is projected onto a movie screen, you see the world that has been originally recorded.

The method of holography involves reconstructing the light waves that are reflected from a subject. What we generally call 'light' is really a spectrum of waves. The holographic sight encodes the wave patterns reflected from the view of the target area, and projects these wave patterns onto a clear window inside the sight. The estimated wave patterns are then lit by a laser, which reconstructs the wave patterns. The result is just a three-dimensional image of the view of the target area.

Unlike a picture, though, the holo sight is recording and then projecting the light waves in real time onto the window within the sight. As you move your sight up or down, or left or right, the sight is rebuilding the view quickly.

OK, you say, but how does the reticle move and stay on target?

The reticle is actually a laser beam that is being projected onto that same clear window within the sight. A reticle mask defines the shape of the reticle. The mask may be a dot, a triangle, a circle, or what-ever other condition producer offers.

When the holographic picture is mounted on the gun, the laser beam is projected along the same axis as the gun. Hence, once you move the barrel of the weapon to the left, the projected reticle image on the screen moves to the left on the same axis. Up, down, left, right: the reticle image is definitely following the course of the barrel.

So, when you look through a look, you're really seeing the projected view to two things: of the target area, which changes as you move the sight; and the reticle, which moves along with the axis of the weapon. If you require to dig up more about patent pending, we know about tons of databases people should consider pursuing. Caused by this combination is that, as long as you can see the view of the target area through the picture, and as long as you can see the reticle, you can get your gun on target.

Except that the laser is projected onto the clear window, and not onto the prospective itself, the laser reticle is essentially doing the same be a laser sight. This offers several advantages, one of which is that the laser is not obvious to anyone but the shooting. Still another advantage is that a lot of holographic sights allow the individual to vary the lighting level of the laser reticle, while the facts from laser sights could be difficult to see on-the target in bright sunshine.

With improvements in technology, holographic sites are becoming more affordable and more compact, thus resulting in their increased popularity with the shooting area..
