How come a Pixelized Soldier Uniform cannot be seen by night vision goggles ?

Question

Is it true that the new uniform cannot be seen by Night vision goggle ?

What is the logic behind ?

Any big tecnology used ?

Answer 1

it is bullsh!t.

the pixels of uniform are well below the resolution of ANY NVG. Thus, and average value of shades of grey within one sensorof the  input chip of the goggles is used, amplified, and projected in the native resolution of the goggles itself.

regardless of the texture, the object would be visible, if moving or contrasting with its background.

the real effect of the cammo is that it effectively blends the lines - better than the common curved patterns. Any straight line is focused on and attracts >human< attention.

experiment>

have a photo of a normal camouflage uniform and a ACU uniform, in the same resolution and size. now use a graphic program to turn them into shades of grey - simulates the low light illumination and receiving. Now RESAMPLE the picture into 1/10 - 1/100 of its original size depending on the original size - to have the cammies recognisible as a silhouette. now resize /inflate/ the images into original size /size, not resolution/. now compare the images with their soources - actually the analogue /previous cammo/ happens to be digitalised, too due to processing through the digital device.

edit>related ot the use of IR light - some devices may actually use an artificial source of light - IR being and obvious colour cause it is not visible by human eyes but the IR can be effectively captured by the input chip of most moccomn digital cameras as a valid source of artificial light - it is even used to supplement the flash light on some occasions. However the principle is dramatically different from the FLIR passive imaging, which ONLY operates with various wavelenghts of various IR sources to evaluate the hot and cold surfaces - quite a different story.

why to use them then?

because the most likely surveilance system of the enemy will be the bare human eye - the optical camera with best resolution so far /when compared ot man made objects/. More than that the camera is employed with cognitive system that interprets the image into meanings - and key ot interpreting is >recognising shapes< a monolitic single colour uniform forms a bigger, more obvious shape than camouflaged one. still, the traditional cammo provides sharp edged lines that can attract the attention. with the digital pattern there are no straight or curved lines longer than the pixel - this bypases the principle of shape recognition - you have no visible contrast of two colours along one line. that is the theory.

Answer 2

I was able to see other Soldiers with my PVS-14s.

I think night vision works by using available light from stars, the moon and so forth.

Answer 3

no you can still see them in night vision. and no night vision does not use the heat of the body like some wana bee's think.  it just can recognize shapes in really low light. the logic is that even in the old bdu, dcu, patters they repeat, on on person you can't tell but a group of people you can tell very quickly because the image is not broken up,  the new digital picture  never repeats so it won't make a defined patters.  and as far as the new acu(blue) pattern the army wears, it is that same as why they say to paint a room blue,  its soothing because blue is a color that doesn't attract the eye to it. i though it was crazy to until driving on post i almost hit some one because i did not notice they were on the side of the road waiting to cross. i could still see them but my eye was not drawn to him.

Answer 4

You can still see them and if you wash your uniforms in certain detergents or get them starched you really stand out at night and make a great target for someone that has an NVG unit on and wants to take a shot at you.   For this reason they sell certain types of detergents in the commissary for washing your uniform and tell you not to get them starched ever if they are ones that you are going to be using in the field.

Answer 5

Not true.  Night vision goggles detect the heat of the body, not the uniform.
