| 摘 要： | 本文对Diels型光学相关器做了重要改进。提出临界延迟速度概念,合理地设计了延迟系统,仅靠改变电机电压即可获得强度和相位相关曲线。指出相位相关曲线携带了脉冲宽度的信息、并预期利用该曲线可更精确地测得脉宽。

| Abstract: | We have improved the correlator developed by J. -C. Diels. In the new type it is consisted of only four prsims; and henoe three pairs of glued optical surfaces become unnecessary. The angle tolerance of prisms is less than 5 second. Auto-ajustment method with prisms is presented in this papers We have designed a reasonable system fyr transmission in which the intensity and phase correlation curves are obtained by onlp changing the voltage applied on the motor.
It is worth pointing out that the phase correlation curve carries information of pulsewidth, which can be measured more accurately from the phase correlation curve. |
