Abstract
Dichromated poly(acrylic acid) films with dimethyl formamide have been used as a real-time recording medium for volume transmission hologram s. In this study a simple computer-generated holographic grating with a sinusoidal amplitude profile is copied onto this recording material by the contact-copying technique. The experimental setup for the conta ct copying of a computer-generated hologram (CGH) is explained, and th e phase modulation is observed for a different exposure time. Theoreti cal and experimental diffraction efficiency values for the CGH copy ar e also evaluated. Photographs of the original and copy of the CGH on t he photopolymer film are presented.
