	Periscope - Wikipedia, the free encyclopedia
		This form of periscope, with the addition of two simple lenses, was used for observation purposes in the trenches during World War I.
		Periscopes, in some cases fixed to rifles, were used in World War I to enable soldiers to see out of the trenches.
		Periscopes were also extensively used in tanks, enabling drivers or tank's commanders to inspect the situation without leaving the safety of the tank.

	Periscope rifle (Site not responding. Last check: 2007-10-01)
		The periscope rifle was invented in May 1915 by Lance Corporal William Beech, 2nd Battalion, a builder's foreman: this device allowed a soldier standing in a trench to take accurate aim and fire without exposing himself to the enemy.
		The upper mirror of the periscope was so fixed that it looked along the sights of a rifle; this image was reflected in the lower mirror, into which the soldier peered.
		Though less effective than conventional rifles, the periscope rifle proved to be a useful weapon, and it was soon in use in many front-line trenches, in particular at Quinn's Post, where the closeness of the opposing trenches had earlier made it virtually impossible to fire a shot by day.

	Submarine Periscope Manual - Chapter 1
		Essentially, a periscope consists of a vertical tube with a head prism inclined to the horizon at an angle of 45 degrees, a reducing telescope, and, at the bottom of the tube, an enlarging telescope and a lower prism facing the head prism and parallel to and below it.
		Periscope specifications often state that no lens or glass plate should be in or near a focal plane except the crosswire reticle, which must of necessity be placed in a focal plane.
		The construction of the periscope is such that the optics and internal mechanism may be easily disassembled and correctly reassembled, and the hermetical tightness of the instrument may be maintained.

	Submarine Periscopes and Approach Techniques
		This dial is duplicated on the back of the periscope, so that the reading may also be taken by the approach officer without requiring the captain to remove his eye from the eyepiece.
		When the periscope is aimed directly at the bow of the sub the bearing is zero, as target bearings are given relative to the heading of the submarine.
		The periscope optics are marked in degrees in both the vertical and horizontal axes.

	Howstuffworks "How Photonics Masts Will Work"
		Periscopes on submarines may be as long as 60 feet (18 m).
		Because of the length of these periscopes, having two mirrors attached inside the ends of the periscope is not a sufficient method for carrying an image from the top window to the eyepiece.
		In a submarine periscope, prisms are used in place of mirrors at the top and bottom of the periscope tube, aligned parallel to each other.

		It can be performed with the periscope installed in the submarine; however, when the temperature is under 50 degrees F it is preferable that it be done ashore or on a tender, to take advantage of higher temperature, and to maintain the safety factor.
		When the periscope is near the horizontal position, locate the clamp carriage in the proper position, with the upper half of the clamp hinge of the clamp carriage open.
		Roll the periscope by means of the wheels on the clamp carriage and the hinge carriage to the inboard transfer opening of the upper deck (Figure 2-44).

		PeriScope directional, deep imaging-while-drilling service is a winner of HART'S E&P 2005 Special Meritorious Awards for Engineering Innovation (237 KB PDF).
		PeriScope directional, deep imaging-while-drilling service is revolutionizing well placement by giving you an unsurpassed ability to see the reservoir as wells are being drilled.
		The PeriScope service clearly indicates the best steering direction, and the deep measurement range gives you an early warning that steering adjustments are required to avoid water or drilling hazards or to avoid exiting the reservoir target.

	Science Explorer: Up Periscope! Build a mirrored tube to see around corners and over walls
		To make a periscope from a 1-quart milk carton, your mirrors must be smaller than 31/2 inches in at least one dimension.
		In your periscope, light hits the top mirror at a 45-degree angle and reflects away at the same angle, which bounces it down to the bottom mirror.
		Periscopes in tanks and submarines have magnifying lenses between the mirrors to make the reflected image bigger.

	USS Bowfin - Periscope (Site not responding. Last check: 2007-10-01)
		The essential function of a periscope is to give an officer conning a submarine a view of the surrounding horizon while his vessel remains submerged.
		Although advances have been made in the development of the instrument, the basic principle is still the same today: the reflection of objects through mirrors or prisms arranged in a tube.
		If a periscope favoring any one of these factors was produced, such favoring was only at the expense of the other factors; hence, the final design generally was a compromise.

	periscope
		This periscope has an extra feature by which you not only can spy objects over walls and around corners, but also which will show that as you turn one end of the periscope the images turn also.
		This simple periscope has a limited view because it is restricted by the solid angle subtended by the periscope exit end at your eye.
		The field of view of these instruments, however, is more than just the solid angle subtended at the other end of the pipe, because the real periscope has a much more complicated telescope-like design included in the periscope.

		Periscope enables professional display of the screen of a Pocket PC onto a nearby PC or laptop for projection, and can also remotely control a PowerPoint presentation (now with DRAWING).
		However, I there is a great deal of utility with the other feature of "Periscope", that being the ability to display the Pocket PC screen on the desktop or laptop computer.
		The only thing that I would recommend, as an upgrade to "Periscope" would be the ability to scribble or write on the Pocket PC screen and have that appear on the desktop or laptop screen.

	Periscope: Declarative and Efficient Querying for Biological Databases
		Furthermore, many of the data sets that are used in life sciences are growing at an astonishing rate, and the queries that are posed against these data sets are also increasing in complexity.
		The key motivation behind the Periscope project is that DBMSs employing a declarative paradigm can play a significant role in managing these data sets and efficiently answering these complex queries.
		As part of this project we are currently investigating declarative methods and efficient algorithms for querying on biological sequences, protein secondary and tertiary structures, and protein interaction networks.
