In this article realization of logic gates through Fourier transform Infrared Spectroscopy (FTIR) spectral signatures is elaborated. A term opto-logic state is defined in such a way that any of the four spectral signatures (756 cm−1,1520 cm−1,2900 cm−1 and 3500 cm−1) assumed either logic-0 or logic-1 values depending on the preset conditions. As a representative case three 2-input logic gates namely OR, AND and Ex-OR are derived. The input to these gates is treated with the four spectral signatures namely 756 cm−1, 1520 cm−1, 2900 cm−1 and 3500 cm−1 derived from two mesogens namely 12BAO and 3BA. Thus four combinations of 00, 01, 10 and 11 are retrieved from the above mesogens. The output of OR, AND and Ex-OR gates are read through the FTIR spectra of Pentyl benzoic acid referred as 5BA, Nonyloxy benzoic acid & pentyl benzoic acid referred as 9OØ5 and Nonyloxy benzoic acid & ethyl benzoic acid referred as 9OØ2 respectively. Thus a proper selection of FTIR spectral signatures along with the corresponding mesogens can be experimented in realizing any desired gate.

通过液晶理解逻辑门

本文阐述了通过傅立叶变换红外光谱(FTIR)光谱签名实现逻辑门的方法。一个术语光电逻辑状态以这样的方式定义的任何四个光谱特征(756厘米-1,1520厘米-1,2900厘米-1和3500厘米-1)假定任一逻辑0或逻辑1的值取决于预设条件。作为一个代表性案例,推导出了三个2输入逻辑门,即OR,AND和Ex-OR。输入到这些门是与四个光谱特征处理即756厘米-1,1520厘米-1,2900厘米-1和3500厘米-1衍生自两种介元,即12BAO和3BA。因此,从上述介晶中检索出00、01、10和11的四个组合。通过分别称为5BA的戊基苯甲酸,称为9OØ5的壬氧基苯甲酸和戊基苯甲酸和称为9OØ2的壬氧基苯甲酸和乙基苯甲酸的FTIR光谱读取OR,AND和Ex-OR门的输出。因此,可以在实现任何所需的门时试验FTIR光谱特征以及相应的液晶元的正确选择。
