Paper Abstract

We demonstrate a phase imaging method based on a single-pixel camera based on a complex-amplitude representation to measure a surface profile of objects. The use of the complex-amplitude representation of the input signal and the phaseshifting technique enables us to perform the phase imaging of an object, that is, the profilometry. The complex-amplitude mask can directly represent the Hadamard patterns that have the positive and negative values. The complex-amplitude masks are displayed on phase modulation mode liquid crystal on silicon spatial light modulator (LCOS-SLM). Furthermore, the residual area is used for the reference beam with the phase shifting. Therefore, the phase imaging system with the coaxial structure has high stability for external disturbances.
