To develop a single-pixel quantitative phase imaging method that extracts spatial phase information through complex Fourier spectrum sampling.
Interfered a digital micromirror device-driven wavevector-varying plane wave with a stationary reference beam to project dynamic spatial frequencies onto the target.
Acquired complex Fourier spectra with a single-pixel detector using four-step phase-shifting and reconstructed phase distributions via inverse Fourier transformation.
Implemented compressive sensing to recover phase images from sub-Nyquist measurements to accelerate data acquisition.
Successfully reconstructed quantitative phase distributions from two digital phase objects using inverse Fourier transforms.
Demonstrated accurate phase image reconstruction from sub-Nyquist sampling rates using compressive sensing, significantly speeding up acquisition.
Characterized the orbital angular momentum of optical vortex beams for prospective multiplexing in optical communications.
