Headline text[edit]

It was suggested that this article should be renamed Night vision. The vote is shown below:

  • Support. Hyphen is unnecessary. — Knowledge Seeker 22:47, 20 Jun 2005 (UTC)
  • Support Actually, hyphen is incorrect, in a noun. Night-vision goggles give you better night vision. Michael Z. 2005-06-21 05:32 Z
  • Support It's a noun. Wood Thrush 03:04, Jun 23, 2005 (UTC)

This article has been renamed as the result of a move request. violet/riga (t) 4 July 2005 21:48 (UTC)

LED reference[edit]

I've added a link to this page in the Light-emitting_diode article but also a note in its talk page disputing both the choice and reasons for the choice of colours of lights for protection of night vision. Anybody with more authoritive understanding than me care to have a look and maybe make a correction to that article? EdDavies 11:20, 5 December 2005 (UTC)

X-Ray Sony Camera[edit]

Would it be appropriate to include, on this page, a discussion (refutation or confirmation) of the fabeled early version of Sony NightShot which, when used during daylight, allowed viewing and recording of "x-ray" images?

Night Vision Technology History[edit]

I believe this article needs some manner of elaboration on the history of night vision technology. Sadly, I cant provide this information. Here's hoping someone else can.AJ 1st 22:04, 30 August 2006 (UTC)

Given that Spicer was no more than 16 years old when WWII ended, the statement in the article as written is extremely unlikely. In the linked obituary, it indicates that he contributed to night vision while at RCA in the 60s. Unfortunately, I don't know enough about the subject to contribute or correct this. —Preceding unsigned comment added by 75.57.86.59 (talk) 21:36, 28 June 2009 (UTC)

HELP[edit]

This article needs lots of corrections (spelling and so forth) attention, and expansion -- you can help. --Lperez2029 00:20, 9 December 2006 (UTC)

BMW, 'night vision in veicles'[edit]

Is somebody is trying to use this as advertising for BMW? The 'night vision in vehicles section' is packed with advertising crap. If night vision in vehicles improves saftey, then cite a reliable source, for example a study. "BMW.co.uk" is not academically reliable. BMW has already been in trouble for trying to rig their Google page-rank, but wether this is actually them, it's still junk so whoever it is please don't revert it again. —The preceding unsigned comment was added by 81.151.172.82 (talk) 15:11, 22 January 2007 (UTC).

Image intensifier[edit]

This segment looks incorrect. As far as I can remember, older image intensifiers use a light sensitive material that phosphoresces when energized by a photon (for example, green phosphorous) and newer models use a photodiode-signal amplifier circuit-LED combination ... ? axharr (former USN) —The preceding unsigned comment was added by 63.149.90.140 (talk) 14:26, 19 March 2007 (UTC).

Green?[edit]

Can anyone tell me why nightvision is green? 81.105.217.34 16:37, 24 April 2007 (UTC)

It mentions this in the image intensifyer page. its green becuase the human eye is most sensitive to this color, and can see the most shades of this color.

needs a non biological section on night vision[edit]

I served on submarines and remember well having to prepare myself for watch (involving periscope) by having the control room dark for a while before needed. TCO 21:04, 13 July 2007 (UTC)

BMW and Night Vision[edit]

BMW source their night vision system, as they do their forward collision system and lane deviation warning system from Siemens VDO, who in turn source it from Mobileye of Israel who obtained the technology from Raytheon (US). Mobileye have signed up most of the major car manufacturers and from 2008 night vision will be offered by most of the major manufacturers. --Gaptech 10:28, 11 August 2007 (UTC)

amplification in image intensifiers[edit]

The section on image intensifiers states that they do not 'amplify' I *believe* that they in fact do, just not in the commonly percieved way; an electronic signal amplifier, such as found in a stereo. My understanding is that the image intensifier unit is a specialized photomultiplier, and the effect is in fact 'amplification'. Once I've verified this, I'll be editing to this effect, that they do in fact 'amplify', but not through the use of amplifier circuits, but photomultipliers sensitive to IR. —Preceding unsigned comment added by 68.116.67.106 (talk) 07:07, 16 December 2007 (UTC)

Merger to IR signature[edit]

No to merger, IR detection is but one form of the technology, and would not be appropriate to for example natrual night vision (we're hopelessly lacking in this article in that respect), image intensification and for that matter systems which used an external IR lamp to illuminate a target.KTo288 (talk) 19:58, 10 June 2008 (UTC)

Bad[edit]

This article is bad. Where is all the information on natural night vision, the link to "eye adaptation" gives me nothing. 84.92.169.252 (talk) 15:19, 3 June 2010 (UTC)

Well, bub, WP:SOFIXIT. I doubt any editors here will disagree that it should have some material on natural adaptation to low-light. So look up some sources, start a section, and start writing! I think something about natural dark adaption should go in lead section also, but not until the article itself says something to summarize. Such as: how much better are we at light detection when dark adapted? What is the quantum efficiency (I recall humans are within a factor of 3 of as good as we can be). How much better ARE animals with a tapetum? They look cool, but what is the payoff? I seem to remember that humans not that bad at night vision compared to most mammals when we are fully-dark adapted-- this article ephasizes that too much. And so on.

Remember, please, that Wikipedia is a collaborative enterprise. You're not being taxed, and you didn't pay, and you're not going to leave a tip, so don't complain about the service! We're all volunteers. Most of us got here by seeing some article and saying "that sucks... even I know more than THAT about that" and starting in on it. Then, you're hooked. So, welcome. Get to work.

Merger of thermal scope??[edit]

Thermal Weapon Sight is a very short stub article which needs to be incorporated into Night vision or Thermographic camera --B. Srinivasa Sasidhar 02:00, 22 November 2012 (UTC)

We don't merge articles just because we can. The Thermal weapon sight is a particular kind of thermographic camera and should be mentioned in the latter article. But no doubt as more specific info becomes available on thermal weapons sights, they will need an article of their own. See WP:SS. Sometimes articles are like redlinks-- you can see that they will need to be a separate article in the future, and there's no point in merging them now, just to have to split them later. For example, we might have a tiny little article on the Fiat PuttPutt XL5. But that's no reason to delete it and cram it into the article on automobiles. SBHarris 02:39, 22 November 2012 (UTC)
