Abstract: In phase-shifting fringe projection profilometry, the nonsinusoidal profile of fringes is one of the most crucial error-inducing factors. Especially, when using nonuniform phase shifts, the ...
Abstract: This letter proposes a novel wideband 360° filtering phase shifter (FPS), which combines a reflection-type phase shifter (RTPS) and two switch-type phase shifters (STPSs). The RTPS is based ...
