ABSTRACT:
A hologram recording device, which comprises a recording layer of a polymer composition a photoconductive element, a second-order super-polarization element and an electron or hole capturing material and having a non-centro symmetric structure is disclosed. Transparent electrode layers are provided on each side of the recording layer. The hologram recording device is capable of space light modulation and real time hologram recording. Also disclosed is a method of manufacturing the hologram recording device and a method of hologram recording using the device. The hologram recording material is of a polymer composition a photoconductive element, a second-order super-polarization element and an electron or hole capturing element. The polymer composition has a non-centro symmetric structure. The hologram recording device according to the invention comprises a recording layer of a polymer composition including a photoconductive element and a second-order super-polarization element. The polymer composition has a non-centro symmetric structure, and transparent electrodes are provided on each side of the recording layer. It is thus possible to provide a hologram recording element, which is suitable for space light modulation and real time hologram recording and which also serves as a phase conjugate device.
