A reflective lensless on-axis digital holographic microscopic system with a spherical reference wave was developed and used to obtain a reconstructed image at several magnification levels. A polarization image camera (PIC) was used to suppress the di

An improved phase retrieval method based the Hilbert transform is introduced to quantitatively calculate the phase distribution from the distorted fringe pattern. Also phase measurement deflectomety is widely used in specular-type samples. The backgr

We used transmission deflectometry to measure the three-dimensional shapes of optical components, and we used the Hilbert transform to retrieve the phases from measured deformed fringe images. Deflectometry is useful for measuring large-scale samples
