Abstract
We created a record of an interference field of reference plane wave and convergent wave in a self-developing photopolymer film using a He-Ne laser and Mach-Zehnder interferometer. Due to Bragg reflections the record acts as holographic lens and transforms the reference plane wave onto a convergent one. To achieve the best performance of the lens the response of the photopolymer film is found and proper conditions for recording are determined. After successful recording the optical parameters of the lens – focal length and diffraction efficiency are measured and compared with values following from the theory. The formed holographic lens has focal length f = 160 mm and reaches diffraction efficiency of 78% at Bragg angle. The used photopolymer meets criteria for the purpose of creating various holographic optical elements.
