Instrument to measure and trace vibration

A mechanical vibroscope.

**Vibroscope** ([Latin](/source/Latin_language): *vibrare* 'vibrate' + [scope](https://en.wiktionary.org/wiki/-scope)) is an [instrument](/source/Measuring_instrument) for observing and tracing (and sometimes recording) [vibration](/source/Vibration).[1][2]

For example, a primitive mechanical vibroscope consists of a vibrating object with a pointy end which leaves a wave trace on a [smoked](/source/Aerosol_impaction) surface of a [rotating](/source/Rotation) [cylinder](/source/Cylinder_(geometry)).[3]

Vibroscopes are used to study properties of substances. For examples, [polymers](/source/Polymer)' [torsional](/source/Torsion_(mechanics)) modulus and [Young's modulus](/source/Young's_modulus) may be determined by vibrating the polymers and measuring their frequency of vibration under certain external forces.[4] Similar approach works to determine [linear density](/source/Linear_density) of thread-shaped objects, such as [fibers](/source/Fiber), [filaments](/source/Natural_fiber), and [yarn](/source/Yarn).[5]

Vibroscopes are also used to study sound in different areas of the mouth during speech.[6]

[Jean-Marie Duhamel](/source/Jean-Marie_Duhamel) published about an early recording device he called a vibroscope in 1843.[7]
