The optimal intensity noise suppression of a Fabry-Perot (FP) laser is experimentally acquired by relatively strong external optical injection locking technology.
采用较强的外注入光锁定FP激光器，获得了理想的强度噪声抑制效果。

Because of optical distortion induced by atmosphere turbulence and limitation of optical devices, acquired images of space object are blurred and degraded.
由于大气湍流等引起的光学畸变和光学系统本身的限制，使得获取的目标图像出现模糊和降质。

Optical sensor target recognition extracts the characteristic of target to perform target recognition after having acquired its reflection and radiation (spectra) characteristics.
