Abstract

A complex amplitude imaging method based on a single-pixel camera architecture with a complex-amplitude representation is proposed. The use of the complex-amplitude representation of the input signal and the phase-shifting technique enables us to perform the phase imaging of an object, that is, profilometry. The complex-amplitude representation of the optical coding masks and a coherent addition that is performed by interference 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 of the mask is used for the reference beam with the phase shifting. Therefore, the complex amplitude imaging system with the coaxial structure has high stability for external disturbances.
