摘要
激光方向性强,单色、相干性好,这些特点使得激光测距可以应用在多个领域。由于相位法测距可以达到较高的精度,因此相位法测距成为激光测距的首选。文中根据激光测距的特点,从几方面对相位法测距进行了改进和优化。在保证精度的前提下,减少了对单片资源的消耗,使激光测距系统有更快的响应速度和更多的资源进行功能扩展。通过仿真验证,文中所提方法达到了预期效果,并可根据不同精度需求,灵活地设计程序。
With the advantage of well directional property, good monochromaticity and strong coherence of laser, laser range finder can be used in many fields. Because the measurement of phase difference has high accuracy, it has become the best choice of laser range finder. In this paper, in consideration of the characteristics of laser range finder, several improvements are made for measurement of phase difference. On the premise of ensuring accuracy, the recourse consumption is reduced, so that the laser range finder can have faster response and more resources for function extension. Simulation results verify that the proposed approach achieves desirable results with a flexible program design on requirement of different precisions.
