<p>to reduce the chance that the rangefinder can be <a href="page.php?w=Electronic_countermeasures">jammed</a>. It is possible to use <a href="page.php?w=Doppler_effect">Doppler effect</a> techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast.</p>

<p>The precision of an instrument is correlated with the <a href="page.php?w=rise_time">rise time</a>, divergence, and power of its laser pulse, as well as the quality of its optics and onboard <a href="page.php?w=Digital_signal_processor">digital signal processing</a>.</p><p>
