To solve the cross-sensitivity to temperature of fiber Bragg grating (FBG) strain sensor, an effective method is firstly proposed for the discrimination of strain and temperature by using a single FBG adopting a special compensated structure, which is bas
A mathematical model of the mirror misalignment of a four-equal-sided nonplanar ring cavity is established in this letter. The variations in the optical axis are discussed through an augmented 6 \times 6 ray matrix formulation. Numerical analysis shows t
Several approaches for fast generation of digital holograms of a three-dimensional (3D) object have been discussed. Among them, the novel look-up table (N-LUT) method is analyzed to dramatically reduce the number of pre-calculated fringe patterns required
