Definition
- Noun:
- An instrument for measuring angles: A goniometer is a device used to measure angles, particularly in scientific and technical fields.
- A direction finder for radio signals: In radio communications, a goniometer is a specific type of direction finder that determines the angular direction from which incoming radio signals originate.
Usage
- The primary use of a goniometer is for precise angular measurement.
- In radio technology, a goniometer is a key component for locating the source of transmissions.
Examples
- Noun:
- The crystallographer used a goniometer to measure the angles between the faces of the mineral.
- The naval vessel's goniometer quickly pinpointed the bearing of the distress signal.
Advanced Usage
- "Optical goniometer": A device used to measure the angles between the faces of crystals or other reflective surfaces.
- An optical goniometer is essential for identifying minerals based on their crystal structure.
- "Radio goniometer": The component within a radio direction-finding system that determines the signal's angle of arrival.
- The old shortwave listening post was equipped with a sophisticated radio goniometer.
Variants and Related Words
- Goniometric (adj): Pertaining to the measurement of angles.
- The goniometric data was recorded for analysis.
- Goniometry (n): The science or process of measuring angles.
- Crystallography relies heavily on the principles of goniometry.
Synonyms
- Angle measurer: A general term for a device that measures angles.
- Direction finder: A device for determining the direction of something, especially radio waves (this is a specific application of a goniometer).
Related Phrases
- "To take a goniometer reading": To use a goniometer to obtain an angular measurement.
