How Interferometers are used as Position Sensors
Interferometer sensors employ energy in the form of light or sound to make precise position/location measurements. There are a number of applications where accurate measurement of very small linear mechanical displacements and distances between objects in the order of nanometers … Read more
What is Calibration of the Sensor?
Calibration of the sensor is the relationship between the physical measurement variable input and the signal variable output for that specific sensor. Typically, a sensor or an entire instrument system is calibrated by providing a known physical input to the … Read more
