Phase-shifting interferometry based on induced vibrations.
The presence of uncontrolled mechanical vibrations is typically the main precision-limiting factor of a phase-shifting interferometer. We present a method that instead of trying to insolate vibrations; it takes advantage of their presence to produce the different phase-steps. The method is based on spatial and time domain processing techniques to compute first the different unknown phase-steps ...
متن کاملPhase-Shifting Interferometry for RF Phase Measurement
This paper introduces an interferometric technique for the phase measurement of microwave devices. A handheld vector network analyzer (VNA) is presented for HF and VHF applications. A wideband synthesizer with multiple synchronized outputs is developed for extending the frequency range to the microwave band. The phase differences between the output signals can be set digitally with sub-degree a...
متن کاملPhase-shifting Gabor holography.
We present a modified Gabor-like setup able to recover the complex amplitude distribution of the object wavefront from a set of inline recorded holograms. The proposed configuration is characterized by the insertion of a condenser lens and a spatial light modulator (SLM) into the classical Gabor configuration. The phase shift is introduced by the SLM that modulates the central spot (dc term) in...
متن کاملSpatial Phase-Shifting Interferential System on Polarization Interference and Grating Beam- Splitting: Phase-Shifting Error Testing
In spatial phase-shifting interferential system on polarization interference and grating beam-splitting, the azimuth errors of the polarizers are the central error sources of phase-shifting steps and have 1:1 effect for the steps. It applies two ways to determine the azimuth errors of the ploarizers: experimental testing and software calculating. The basic principle of experimental testing is t...
متن کاملPhase-Shifting Scatterplate Interferometer
The advantages of common path interferometers for reducing effects of vibrations are well known. A scatterplate interferometer is one common-path interferometer that is well suited for the testing of large concave mirrors, however due to the common path characteristics it is difficult to perform phase-shifting. This paper describes a phase-shifting scatterplate interferometer where the phase-sh...
