A positioning goniometer or goniometric stage is a device used to rotate an object precisely (within a small angular range) about a fixed axis in space.
A positioning goniometer or goniometric stage is a device that rotates an object precisely about a fixed axis in space. It is similar to a linear stage —however, rather than move linearly relative to its base, the stage platform rotates partially about a fixed axis above the mounting surface of the platform.
This Royal Navy model is typical of B–T goniometers. The two sets of field coils and the rotating sense coil are visible.. A Bellini–Tosi direction finder (B–T or BTDF) is a type of radio direction finder (RDF), which determines the direction to, or bearing of, a radio transmitter.
The various procedures for radio direction finding to determine position at sea are no longer part of the maritime safety system GMDSS, which has been in force since 1999. The striking cross frame antenna with attached auxiliary antenna can only be found on the signal masts of some older ships because they do not interfere there and dismantling ...
The most common type of goniometer is the "kappa goniometer", which offers three angles of rotation: the ω angle, which rotates about an axis perpendicular to the beam; the κ angle, about an axis at ~50° to the ω axis; and, finally, the φ angle about the loop/capillary axis. When the κ angle is zero, the ω and φ axes are aligned.
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
