摘要
要利用全息技术对本振光束进行调制以实现与信号光束的匹配，进而提高外差效率的原理及实施方法，介绍了作为调制器用的全息位相光栅的研制技术，为在外差探测系统中应用全息技术提供了依据。
This paper discusa the pnindple and measure of increasing beterndyne efficiency by contmling the local oscillator beam used by the holographic technique and rediantg the local oscillator team match signal beam, and giuing technique of raearchiing and pmdudng .in holograghic grating on a conditioner. It provides a basis for using the holographic technique in the beteradyne detedion system.
