meanwhile ,wea photoelectricity signal disposal technique is further discussed ,by means of phase locking amplifying in the paper ,weak signal is disposed and amplified 106 times and its Signal/Noise (S/N) can be improved 1000 times .

• 同时对微弱光电信号处理技术也作了较全面深入的研究。 本论文是应用锁相放大的方法进行微弱信号处理的，放大倍数为10~6，信噪比改善可达1000倍。
