In the late 1940s, the Radioplane Company developed a set of prototypes of the Q-1 target series, which used pulsejet or small turbojet engines. Although the Q-1 series was not put into production as a target, it did evolve into the USAF RP-54D / XB-67 / XGAM-67 Crossbow anti-radar missile, which was first flown in 1956.
The basic layout of a collimator sight is a closed tube with a lens at its open end and a luminous reticle mounted near the closed end at the focus of the lens, creating an optical collimator. The reticle is illuminated by an electronic light source (an incandescent light bulb or, more recently, a light-emitting diode ) or by ambient light ...
Reticle of Bell & Howell Pocket Comparator Reticle accessory (PD-8) used in sniper rifles A reticle , or reticule [ 1 ] [ 2 ] also known as a graticule , is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight , spotting scope , theodolite , optical microscope or the screen of an ...
An optically ideal 10× sight in this example has been perfectly parallax corrected at 1,000 meters (1,094 yd) and functions flawlessly at that distance. If the same sight is used at 100 meters (109 yd) the target picture would be projected (1000 m / 100 m) / 100 mm = 0.1 mm behind the reticle plane.
Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs. Compact digital cameras DMC-LC5 [ 1 ] and DMC-F7 [ 2 ] were the first products of the Lumix series, released in 2001.
Using an LED as a reticle is an innovation that greatly improves the reliability and general usefulness of the sight: there is no need for other optical elements to focus light behind a reticle; the mirror can use a dichroic coating to reflect just the red spectrum, passing through most other light; and the LED itself is solid state and ...
