Analysis of diffractive optical elements generated onto photopolymer materials using a liquid crystal display

We produce phase-only diffractive optical elements (DOE) onto photopolymer. To this goal we use a liquid crystal display (LCD), displaying the DOE amplitude master, which is imaged onto the photopolymer. Various challenges need to be overcome such as accurate combined control of LCD and photopolymer and proper imaging of the master onto the photopolymer plane, which will be presented in the paper.This work was supported by the "Ministerio de Economía y Competitividad" of Spain under projects FIS2011-29803-C02-01 and FIS2011-29803-C02-02 and by the "Generalitat Valenciana" of Spain under project PROMETEO/2011/021
