Non-contact displacement sensors are increasingly being adopted across industries for their precision, reliability, and ...

Abstract: The Mach-Zehnder and Sagnac hybrid fiber optic interferometer (MZSI) is widely applied in numerous fields and capable of retrieving phase signals with the application of the appropriate ...

Abstract: Lateral shearing interferometry is an effective method for directly measuring the depth gradient of aspherical surfaces. To address the low phase reconstruction accuracy resulting from the ...
