在室温下，用Sr_（0.75）Ba_（0.25）Nb_2O_6晶体制作了光折变全息图。固定的全息图可以直接读出或施加正电压脉冲后读出，这可以显著提高衍射效率。记录并固定单个光栅以及图像。
Photorefractive holograms stored in Sr0.75Ba0.25Nb2O6 crystals are electrically fixed at room temperature. The fixed holograms can be read out directly or after a positive-voltage pulse is applied that can dramatically enhance the diffraction efficiency. Single gratings as well as images are recorded and fixed.
