摘要
本文对半导体激光器的直接电流调制特性进行了综合性的讨论,对影响其频移特性的因素进行了分析。在此基础上,对低频范围内半导体激光器随调制电流变化的频率调制特性对FMCW技术的影响进行了讨论。
In this paper,the characteristics of semiconductor laser diode whose current is directly modulated are described synthetically.Several factors that limited the frequencyshift property of semiconductor laser diode are analyzed simultaneously.Moreover,the influence caused by the freqeuncymodulated laser diode used in FMCW measuring system in low frequency domain is also discussed.
