| Abstract: | Bacteriorhodopsin (BR) is a kind of light sensitive protein with excellent anti-fatigue property and high optical transition quantum efficiency,by which optical image information can be acquired and stored.The relationship between the space distribution of BR light absorption variation and the grey value distribution of the stored image has been discussed.The experimental study on gray-level characteristic of BR,using the genetic manipulation of the BRD96N film as a sample,has been done by the self-made system.Excellent grey value exhibition ability has been shown by this experiment. |
| Keywords: | Bacteriorhodopsin film (BR film) Storage of image information Gray-level characteristic |
