Goniometer \Go`ni*om"e*ter\, n. [Gr. ? angle + -meter: cf. F. goniom[`e]tre.] An instrument for measuring angles, especially the angles of crystals, or the inclination of planes.
Contact goniometer, or Hand goniometer, a goniometer having two movable arms (ab, cd), between which (at ab) the faces of the crystals are placed. These arms turn about a fixed point, which is the center of the graduated circle or semicircle upon which the angle is read off.
Reflecting goniometer, an instrument for measuring the angles of crystals by determining through what angular space the crystal must be turned so that two rays reflected from two surfaces successively shall have the same direction; -- called also Wollaston's goniometer, from the inventor.
Wiktionary
n. 1 A device used to measure the angles of crystals. 2 A radio direction finder. 3 (context medicine English) An arthrometer (device for measuring the arc or range of mobility of a joint).
WordNet
n. direction finder that determines the angular direction of incoming radio signals
Wikipedia
A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry is derived from two Greek words, gōnia, meaning angle, and metron, meaning measure.
The first description of a goniometer, derived from the Astrolabe, was apparently in 1538, by Gemma Frisius.
A goniometer is often included in analog audio equipment to display a Lissajous figure which shows the amount of stereo (that is, phase differences) in a dual-channel signal. It allows the sound technician to adjust for optimal stereo and determine the makeup of errors such as an inverted signal. Many goniometers also provide a VU or PPM as a secondary function. A goniometer adapted for surround metering is called a 'jellyfish display'. This term was coined by DK-Technologies A/S from Denmark.
Goniometer may refer to:
- Goniometer, an instrument that measures angles or allows an object to be rotated to a precise angular position
- Positioning goniometer, a device used to rotate an object precisely about a fixed axis in space
- Goniometer (audio), a device that displays the amount of stereo in a dual-channel signal
- The Bellini–Tosi direction finder is also known as a radio goniometer
Usage examples of "goniometer".
While Doc Savage hopefully awaited some spark to come from the dead radio in his headquarters, Ham and Monk believed at the moment all their troubles were concentrated in the failure of their own radio and the goniometer with which they had been following the passenger plane’s radio beam.
Until Ham and Monk had sighted the fog-wreathed summits of Lassen and Shasta, their goniometer had been picking out only a series of dashes.
One day, during an interlude of free flight, he strode into the control-room and glanced at the course-plotting goniometer, then started into the “tank.
Chart after chart he hauled down, and for many minutes he worked with calipers, compass, goniometer, and a carefully-set adjustable triangle.
The tracking stations were equipped with goniometers, apparatus for measuring angles, and each could say within seconds which direction the broadcast was coming from.
