摘要: 本文以多頻率測(cè)距的長(zhǎng)距離相位激光測(cè)距儀電路為基礎(chǔ),提出了采用一只高穩(wěn)定度標(biāo)準(zhǔn)頻率晶體振蕩器來(lái)直接進(jìn)行頻率綜合的一種新電路。分析了該電路的優(yōu)點(diǎn)、性能和技術(shù)指標(biāo)。證明該設(shè)計(jì)方案切實(shí)可行。

Abstract: Based on circuitry of the long distance phase laser range finder with multi-frequency ranging, a new circuit for direct synthesis of frequency by means of a single crystal oscillator of high stability has been proposed Its advantages, performances and technical indices have been analysed. The design method for the circuit is proved to be feasible. -
