Definitions for "Goniometer"
An instrument for measuring angles, especially the angles of crystals, or the inclination of planes.
an instrument used to measure angles. NOTE-Goniometers are frequently used with X-ray diffraction equipment to measure crystal axis angles or for optical angle measurement.
Protractor of 180 degrees with extended arms; used to measure flexibility
direction finder that determines the angular direction of incoming radio signals
a very sensitive low-noise broad-band direction finding radio wave receiver
More commonly referred to as a direction-finder.
A goniometer is often included in analog audio equipment to display 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.
