Programmable hardware timing was used in design of microsecond synchronizer based on ISA bus, after pulse generated by oscillator was divided frequency, it was sent to 8254 to count.
基于IS A总线的微秒级同步器采用可编程硬件定时，由晶振发出脉冲经分频后送入8254计数。

Functional relations between measured linewidth and optical parameters, structural parameters, oscillator coil and high-frequency rectangular pulse Numbers have been derived in the paper.
推导了被测线宽与光学性能参数，结构参数，振荡频率以及高频矩形脉冲数之间的函数关系式。

Bying adding an oscillator mirror in the imaging path, thus the enlarged image will be scanned by the narrower slit, and the optical boundary information is converted into gradient electrical pulse.
