Diffraction model of a laser speckle interferometer for measuring micro-displacements of objects with scattering surface [PDF]
Компьютерная оптика, 2020 On the basis of diffraction transformations of an optical wave field a mathematical model for the formation of speckle modulated interference patterns and signals at the output of a speckle interferometer is developed, which allows us to identify their ...

Measurement of <20 fs bunch length using coherent transition radiation
Physical Review Special Topics. Accelerators and Beams, 2014 By monitoring coherent transition radiation (CTR) with a Michelson interferometer, bunch length measurement was investigated. Less-than-20-fs electron bunches were generated by a photocathode-based linear accelerator (linac) and a magnetic bunch ...

Sinusoidal phase-modulation interferometer capable of measuring 1D displacement and 2D in-plane displacement [PDF]
EPJ Web of ConferencesInterferometers for displacement measurement with picometer resolution are required. The main cause of degradation of interferometer resolution is air fluctuation. To investigate the effect of air fluctuation on displacement resolution, we have developed
