| Abstract: | An exposure control instrument for holograph is designed,which can automatically adjust the object/reference light intensity ratio and the time of exposure in holograph to the best value by liquid crystal light valve(LCLV).This instrument uses LCLV and silicon photoelectric cells subtly,which can survey,adjust and control automatically,and improve the work efficiency of shooting fine hologram obviously. |
