Cool. I think Dave Brooks is a closet Linux geek. ;-) My employer makes some parts for the photonics masts, which are the modern-day periscope replacements. They're basically an extendable pole with an electronics package at the top. Visible and infrared cameras, a laser range finder, antennas, etc. Rather than bouncing light off mirrors, the imagery is carried electronically. Aside from design flexibility, it only needs a small cable junction in the pressure hull. Traditional 'scopes needed a big hole and complicated moving seals. Here's a photo of the top: http://www.navy.mil/navydata/cno/n87/usw/issue_24/images/06_periscope.gif (from: http://www.navy.mil/navydata/cno/n87/usw/issue_24/eyes2.htm) -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
