时空测距法的研究

Study of range-measurement based on time-space domain

提出了一种时空测距方法———使测距系统中的像素探测器高频振荡 ,即进行时空转换 ,通过测量探测器上二次谐波与基波信号之比可获得距离信息 .这种方法原理简单 ,操作方便 ,且可望达到很高的精度 .

It was proposed in this paper, a new method o f range-measurement based on time-space domain. In this method,the pixel-detec tor is vibrated in high frequency, thus there is time information in the pixel -vibration,that is a transformation from time-domain to time-space domain.Thr ough it the range information could be obtained from the ratio of elementary w ave and secondary wave on the detector. This method is simple in principle, conv enient in operation and has high precision as well.
