Nonlinear holographic recording in thermoplastic materials

A model of holographic recording in thermoplastic materials has been developed. The effects of the nonlinear characteristic and the MTF of the material were included in a double Fresnel-Kirchhoff integral to evaluate the reconstructed image. The model was applied to calculate the reconstructed images of microline objects (3 and 5-element Ronchi rulings). The results suggest that it is possible to reconstruct high resolution images from such holograms by optimizing the recording conditions.
