jazjar Posted July 13, 2011 Share Posted July 13, 2011 Look at this! http://www.flickr.com/photos/us_army_rolling_along/5787674762/ It's a miniature crystal ball used by US gunners to find hidden T-72s .:debile2: P.S I know it's not a crystal ball, could anyone tell me what it does? P.S.S look at that magnification for the thermals! 50x LOL! 0 Quote Link to comment Share on other sites More sharing options...

jazjar Posted July 13, 2011 Author Share Posted July 13, 2011 I think so, it's just that finding the functions of all those switches is difficult and secretive. What does that big round glass do anyway? 0 Quote Link to comment Share on other sites More sharing options...
MAJ_Fubar Posted July 13, 2011 Share Posted July 13, 2011 That's the "bioc" or bi-ocular sight (or maybe binocular, I'm sure someone will correct me), and it allows the gunner to scan using the FLIR without having to mash his face in the GPS. By the book you're supposed to scan with the bioc then switch to the primary sight to engage, but most gunners just shoot off the bioc. 0 Quote Link to comment Share on other sites More sharing options...
Mogwa Posted July 13, 2011 Share Posted July 13, 2011 There you have it. The answer from a knowledgeable source. Thx Fubar.Mog 0 Quote Link to comment Share on other sites More sharing options...

tarball Posted July 14, 2011 Share Posted July 14, 2011 Article detailing the differences, vis-a-vis optics and sights:http://www.dtic.mil/dtic/tr/fulltext/u2/a294018.pdfthe gist:monocular: one objective lens, one tube, one eyepeicebiocular: one objective lens, one tube, two eyepeices. Your two eyes (which see in 3D due to offsets) see the same 2-D image sans depth cues.binocular: two objectives lenses, two tubes, and two eyepeices.Makes for some interesting thoughts on depth-cues and the way sights work. In the GPS, since you put an eye up to it, I suppose you are using the markings and lase distance information to mentally substitute for depth cues? Or, with range-finding, I guess visual depth cues don't matter much. Hence, in the auxiliary sites, we use the stadia to help judge sizes and depths?This all makes me think of the robot battlefield that we are supposedly on the way towards. Obviously, since any automation and artificial intelligence will rely heavily on optic sensors, it would seem that these are easily defeated in an environment as kinetic as that of armor on the battlefield. Or, is everyone planning on asymmetric-only battle for the foreseeable future? 0 Quote Link to comment Share on other sites More sharing options...
jazjar Posted July 14, 2011 Author Share Posted July 14, 2011 Wait, so a gunner looking in the BIOC thermal seees a 3D target, or just a 2D one? Also, going back to the original topic ( the P.S, not the joke:) ), a gunner could have his BIOC set to thermal wide viewing mode and his GPS eyepiece to 10x day sights and shoot using that arrangement? ( Although given the advantages of 2nd Generation FLIR with 50x magnification! that would not be very useful.Finally, the eyepiece still has access to the thermal sights, correct? 0 Quote Link to comment Share on other sites More sharing options...

You are looking for silhouettes, and use the laser to measure, or the reticule lines to estimate the range - end of story. 0 Quote Link to comment Share on other sites More sharing options...

Technically the gunner is viewing a 2D scene through the FLIR, it's up to his brain to figure out the depth perspective, and yes, the sight setup you describe is generally how you'd prefer set everything up. Something to remember, magnification levels beyond the optical 13x of the GPS is electronic, so all you're really getting at 50x is interpolation of the 13x image. Oh, and for your last question...yes. 0 Quote Link to comment Share on other sites More sharing options...
