How to make a Hologram

     Holography is described scientifically as a wave front reconstruction process. Unlike a camera which forms and records the two-dimensional image of an object on film, a hologram records and reconstructs the light field propagating from a three-dimensional object to the viewer. A good analogy is the recording and play back of sound. The sound waves (e.g. music) are encoded and recorded on a disk. Upon proper decoding, the original sound waves are reconstructed. With holography, the field is encoded in the form of an interference pattern and recorded as refractive index variations on a clear window. The decoding is achieved by illuminating the hologram with laser light and the light field that was propagating from the object scene to the hologram window is reconstructed. Thus, a viewer cannot tell if the three-dimensional image he sees is "live" or a holographic reconstruction.

     The Holographic sight makes use of the capability of a hologram to construct a three-dimensional image to produce a reticle that is projected out to the target plane. This is achieved by using a large, high quality aberration free lens to project the pattern as illustrated. The reticle image could be of any light pattern, any geometric shape or size, and produced in either 2 dimensional or 3 dimensional form. The holographic reticle is uniformly bright and distortion-free regardless of image size. A parallax free image is created with a large and bright aiming pattern allowing quick target acquisition, particularly in close quarter combat situations. At the same time, the HWS can produce an aim point as small as the human eye can resolve to achieve the highest aiming accuracy possible without magnification.

Troubleshooting

In this section you will find troubleshooting techniques. If these solutions do not solve the problem, please contact KERIF Customer Service Department at customerservice@nitevis.com or by calling (7024) 324-6463.

The sight will not power up:

1. Ensure the batteries are inserted properly according to the diagram on the bottom of the battery cap.

2. Replace the batteries with new, unused batteries that contain a full charge.

3. Inspect the battery contact points in both the battery cap and on the sight itself. These contact points are spring loaded and surrounded by a rubber gasket that may catch the spring. Move the contact points around and ensure they are at or above the surface of the rubber gasket.

4. Reset the electronics by removing any source of power for approximately two minutes. This will allow a capacitor in the electronics housing to drain of power, resetting the electronics. Reconnect the batteries and operate the sight as normal.

5. Check the battery contacts for corrosion or wear. Clean the contacts.

The reticle is fuzzy/ has a 'halo' effect/ has more than one reticle:

The reticle is naturally pixilated and the outer circle will appear to be made up of many small dots. The center circle will still be distinguishable as one dot.

1. Lower the brightness level of the reticle. This fault is generally caused by the reticle brightness being too high. The reticle is not designed to be so bright as to block the target.

2. The reticle is projected onto your target plane. You must focus on it like you would any other object at that distance. Do NOT focus on the sight housing like other reflex sights; focus on your target. The outer ring is designed to be a reference to center, similar to a ghost ring.

3. If you wear corrective lenses for nearsightedness, you will require them to see the reticle in focus as it is projected onto the target plane. If you wear bifocals or have astigmatism, you may see a distorted reticle.

4. Check with others who have used the sight, and compare what you see to ensure it is not your focal acuity prior to turning the sight in for repair.

The reticle is flashing/ flashing on and off/ unit turns off during recoil:

1. This is the low battery indicator. Replace the batteries.

2. If the batteries are low, the weapon platform may still cause the reticle to flash on and off, even before the low battery indicator takes effect. Replace the batteries.

3. Replace the battery with Energizer brand batteries. These have proven to be the most effective to withstanding a consistent amount of recoil. Many brands of batteries deteriorate faster than others and can result in these failures.

There is a streak in the reticle/ the reticle is dim/ the reticle fades in parts of the window:

1. Replace the batteries.

2. Check with others who have used the sight, and compare what you see to ensure it is not your focal acuity prior to turning the sight in for repair.

3. Contact Customer Service.
