Title Laser Interferometers. Laser Interferometry is a mainstay of modern physics, belonging in every physics teaching lab. With this experiment, students assemble and align the interferometer themselves, learning about modern optical components, mounting hardware, and alignment procedures. They observe the interferometer fringes first hand (e.g.

Laser interferometry in space is immune form seismic noise and allows for investigation of Tensile testing of textile fibres. Laser interferometry has been seen by many as a means of measuring fibre diameters Fatigue Cracks: Propagation of Laser Interferometers and Calibration Systems. Keysight’s laser interferometer and laser calibration systems offer high precision in a wide dynamic range, the ability to measure a position with multiple degrees of freedom, and the highest accuracy available in both air and vacuum systems. Laser interferometers are often assumed to automatically provide the ultimate in measurement accuracy.

Laser Interferometer. Laser interferometers have been used to record surface wave pulses propagating on concretes (Chekroun et al. 2009). From: Non-Destructive Evaluation of Reinforced Concrete Structures: Non-Destructive Testing Methods, 2010

Laser interferometry has been seen by many as a means of measuring fibre diameters Fatigue Cracks: Propagation of Laser Interferometers and Calibration Systems. Keysight’s laser interferometer and laser calibration systems offer high precision in a wide dynamic range, the ability to measure a position with multiple degrees of freedom, and the highest accuracy available in both air and vacuum systems. Laser interferometers are often assumed to automatically provide the ultimate in measurement accuracy. However, in reality the situation is more complex. When measuring linear displacements in air with a laser, the performance of the environmental compensation system is particularly important. Laser Interferometers measure distance with extreme accuracy. 1nm is possible.

There are two types of laser interferometers: homodyne and heterodyne. A homodyne interferometer uses a single-frequency laser source, whereas a heterodyne interferometer uses a laser source with two close frequencies.

Precision stabilised laser source. The system design uses the Renishaw XL-80 laser interferometer to compensate for Abbe errors in the measurement system relating to any kind of angular displacement incurred in the setup. This could relate to sliding stage linearity, line scale placement or reflector positioning, for example.
