In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .

在第一部分，对两种新的并行光学布尔逻辑运算方法及系统进行了研究：首次提出并实现了三输入、双输出铸影光学逻辑运算系统及其由此得到的光学全加器，并提出一种以此为基础的3-比特译码器阵列逻辑，首次利用图形编码和不同的读写模式实现了无时序操作的BSO-PROM光并行逻辑运算，大大提高了这种空间光调制器用作光并行逻辑门的运算速度，使之成功地用于光学符号代换之中。

This method also allow us to select the most efficient way from the bulk optical systems and available recoding methods, i.e., identifying the space bandwidth product of the input signal, the minimum size of lens apertures, the sample space and total sample number of CCD and spatial light modulator, the need of magnification before the signal passes through a SLM or when the signal reaches the camera.

通过该方法可以确定合适的加密系统和光学器件，例如输入信号的空间带宽积、变换透镜的最小孔径、空间光调制器的分辨率和像素大小、CCD的分辨率和像素大小以及入射到空间光调制器和CCD靶面上光场所需的放大倍数。
