摘要
针对国内外已有远距离红外激光声探测系统易受大气噪声干扰的缺点,通过理论推导和计算机数字模拟,提出了用强度调制激光探测声振动的方法,可以有效克服大气干扰的影响,具有较大的应用前景。
Aiming at the disadvantage of infrared laser detection system for sound vibration that the signal is disturbed by atmospheric noise, basing on theoretics deduce and computer numerical value simulation, a method of detecting sound vibration through intensity modulation laser beam was presented. The method can suppress atmospheric noise efficiently.
