【Abstract】 The method of designing the holographic field-lens (HFL) with high diffraction ef-ficiency and high angular resolution has been proposed in the paper. The diffraction efficiencyand angular resolution of the HFL with four focusing points made of dichromated gelatin (DCG)have been achieved over 40% and 0.25 degrees, respectively.更多还原
