A Compact Dual-Oblique-Fiber Heterodyne Phase-Shifting Point Diffraction Interferometer

Point diffraction interferometers (PDIs) utilize a near-ideal spherical wavefront generated by point diffraction as the reference, providing a high-quality measurement benchmark independent of reference surface quality. In this work, a compact dual-oblique-fiber heterodyne phase-shifting point diffr...
