Talk:Laser rangefinder

message: This page should either be merged or made more compatible with the LIDAR page.--David Streutker 20:15, 25 August 2005 (UTC)
replies: text: Against merge: IMHO the LIDAR stuff should be removed from Laser range-finder article. In my eyes LIDAR and Laser range-finders are two different sets of devices even if they share the same principle and a LIDAR can also measure distances. Alureiter 16:10, 5 October 2005 (UTC)

text: Against merge. Agree with Alureiter: LIDAR stuff should be moved to LIDAR page and this page should be used for laser rangefinders. Mattopia 11:03, 1 November 2005 (UTC)

text: Against too, I thought of Laser range-finder for gadgets used in construction like Leica Distos (image added) or Bosch DLE. --Marc Lacoste 20:55, 23 May 2006 (UTC)

message: The Laser Rangefinders and 3-D Computer Modelling section is very generic and not complete. The subject is better discussed in the 3D scanner article. I propose to shorten this section a lot an refer to that article.ALoopingIcon 15:50, 24 March 2006 (UTC)

thread_title:  Laser Rangefinders and 3-D Computer Modelling 

message: The article as of today reads "Nikon have a superb product, supplying handheld rangefinders at prices well in line with the rest of sports equipment." This is biased and should not be part of Wikipedia. Maybe Nikon has a very good product, maybe not. Actually I personally believe they have good rangefinders, but they are not the best on the market. I suggest that some important laser range finder companies are listed in the article, but the reader should decide or do his own research, what is "superb".

message: How do they measure something moving at the speed of light?
Dudtz 8/3/06 8:45 PM EST
By measuring phase offset (using an interferometer) between forward and reflected waves, then using the speed of light in m/s to convert the phase offset to distance in m, then displaying meters or converting measured results to yards.  Yaf 20:02, 4 August 2006 (UTC)
thread_title:  How do they measure? 

message: It seems to me that the section currently labeled s "Range" should be "Error" as all the facts presented relate to distortions that result in a loss of accuracy, —The preceding unsigned comment was added by 70.98.76.131 (talk) 05:12, 12 April 2007 (UTC)
thread_title:  "Range" section should be "Error" 

message: If no one disagrees, I'll work on renaming the article to "Laser rangefinder" to remove the hyphen.  As far as I can tell "rangefinder" is the more commonly used spelling.  When I do this I'll make sure to update pages linking to it. Gh5046 (talk) 16:53, 19 June 2008 (UTC)
thread_title:  Hyphen in the name? 

message: There is no reference to commercial products like the Leica Disto, Bosch, Hilti or other lines.
Is there a page for these products - a link would be helpful.
Do they use the same system of measurement? (I doubt it, as their accuracy (+- 3mm) and short range (30-200m) would make timing difficult.)

replies: text: My understanding is that they modulate a continuous beam with an RF sinusoid and measure the phase difference.  This is described in the Time-of-flight_camera article.  -- David Woolley (talk) 13:38, 11 March 2015 (UTC)
thread_title:  Commercial construction products 

message: Although there is a section on laser tape measures, my understanding is that they actually use the RF modulation technique, described near the beginning of Time-of-flight_camera, but there is no mention, in the current article, of this technique, which gets round the extreme timing requirements noted near the beginning of the current article.
Sorry, but I don't have any primary sources to hand at the moment.
Also there seems to be a lot of overlapping articles in this area.
