图像的运动造成光电成像系统的入射能量变模糊，并且降低了系统探测和识别远处目标的能力。在敏感器积分时间或成帧时间所发生的运动通常产生最重要的影响，尽管，帧与帧之间的图像运动也能重点依靠应用处理和图像处理来解决。这样，瞄准线稳定的技术要求仅局限于图像运动的振幅，而没考虑频率也该存在有一定的裕量，及在一些情况下可超出设计的限定值。
The motion of the image blurs the incident energy of the electro-optical imaging system and reduces the system’s ability to detect and identify distant targets. Motion occurring at sensor integration time or framing time usually has the most significant effect, though the motion of the image between frames can also be focused on application and image processing. Thus, the technical requirements for line-of-sight stabilization are limited to only the amplitude of the image motion, and there is a margin of effort regardless of the frequency, and in some cases may exceed design limits.
