This paper presents an analysis of error compensation using a newly modified two-step triangular-pattern phase-shifting measurement method, developed to reduce periodic measurement errors due to gamma nonlinearity and defocus of the projector and camera. Experimental analysis revealed that a trade-o
A novel grating is proposed to produce multi-wavelength output with inscribing phase-shifted fiber Bragg grating (FBG) in polarization-maintaining fiber (PMF). The reflective spectrum of grating is analyzed by a transfer matrix method. The effects of grating parameters on property of the phase-shift
