Digital optical operation in multilateral system by bacteriorhodopsin film
用细菌视紫红质膜实现多进制数字光学运算

Bacteriorhodopsin film has a special property of complementary suppression modulated transmission of yellow and blue beams. Resolving the transmission rate equations of the yellow and blue beams,the analytical formulae are obtained and graphic results are shown. We put forward a multilateral-system computational model of digital optical matrix addition and subtraction operations without carry and abdication respectively. The novel model and frame of basic optical computation are constructed,and the optimized project of digital optical matrix addition and subtraction operations are designed.
