Liu, Hongpeng published the artcileShear deformation response of a holographic sensor based on elastic poly(MMA-co-LMA) photopolymer, HPLC of Formula: 142-90-5, the main research area is methyl lauryl methacrylate Shear photopolymer diffraction wavelength.
A holog. sensor based on camphorquinon doped poly (Me methacrylate-co-lauryl methacrylate) (poly (MMA-co-LMA)) elastic photopolymer is developed for characterizing the shear deformation of material. A shear angle and its transverse displacement, which are induced by a couple of shear stresses, are analyzed using a diffraction spectrum of a transmission holog. sensor. The dependence of the peak wavelength shift on the shear deformation presents a good linear relationship which provides a quant. characterization means. The detectable maximum of the shear angle exceeds 26.1 deg, and the peak wavelength shift closes to 4.0 nm. The available sensitivity is better than 3.33 deg/0.5 nm (shear angle/wavelength shift) using a com. spectrometer with 0.5 nm of resolution Finally, the reversibility response of shear deformation further confirmed the practical applicability of the elastic polymerbased shear deformation sensor. The spectrum measurement of shear deformation provides a novel measurement means for the mech. deformation of materials and expands the application of a holog. sensor.
