Civil War?

The article says "for use in the American Civil War (circa 1891)". Last I checked the War had been over for about 26 years at that point. However, I don't know enough info to correct this sentence to whatever it's supposed to be.--Asimperson 06:18, 3 September 2007 (UTC)[reply]

Remove demo info?

The instructions on how to make a demo periscope are nice, but they seem like they belong somewhere else, say, a wikibook module on optics. Should we take them out? Night Gyr 01:11, 4 Feb 2005 (UTC)

Why prisms?

Why prisms instead of mirrors for the more advanced periscopes? this isn't explained anywhere and it isn't obvious to me

The silver or Aluminum on mirrors degrades (oxidation, rubbing, scratching) over time and has to be replaced like telescopes. Prisms use optical qualities and not materials and are generally sturdier. 143.232.210.150 (talk) 16:46, 20 April 2011 (UTC)[reply]

Scientist

Who was the scientist who invented it? 24.77.42.48 01:03, 16 February 2006 (UTC)[reply]

I've added some names. Samw 03:50, 16 February 2006 (UTC)[reply]

handiscope - a new phenomenon..

the article mentions magnification but there is nothing on how this is done.

Have you noticed that when at crowded events nowadays that rather than push to the front people simply use their cameras - especially video cameras, zoom in, then alter the angle of the viewing screen and hey presto. So I want to name this phenomenon handiscope. It differs from a periscope as this method was not designed as a periscope, there could be two mirrors and they could be prisms, but I do not think that this is the design or the intended design. I have seen it in action before, but at the weekend - I was in Rome and entered St Peters, minutes later the Pope arrived in the room, and I have posted the video on my blog, plus people using their handiscopes.

If you can cite your references, go for it! IMHO the term "handiscope" is new and thus violates Wikipedia:No original research. The phenomena itself is certainly worth documenting as part of the periscope article as it accomplishes the same fucntion. Samw 21:53, 10 April 2007 (UTC)[reply]

I agree with Samw, although no intention to violate Wikipedia. It is a fun development and application of modern technology that a lot of people use. I have put a picture on my blog, not sure it is appropriate here - and that, plus other observations is the sum of my research! David White 21:51, 13 April 2007 (UTC)[reply]

Section really needs a photo of stereo periscope

It is obvious, but for now, will place a link to Coincidence rangefinder. The page mostly thinks naval and cute for kids toys, but lots of professional use is by parallax. 143.232.210.150 (talk) 16:49, 20 April 2011 (UTC)[reply]

what is a pairiscope

something you use to see under water
