Doppler Phase-Shifting Digital Holography

Not Accessible

Your library or personal account may give you access

Abstract

A novel reconstruction method utilizing optical Doppler effect for digital holography is proposed. Phase modulation is performed by moving a reference mirror. The object phase is obtained by the phase of a peak in Fourier spectra of time-varying fringe data. Its applications to interferometry are described, including two-wavelength contouring.
