摘　　要：为了克服井下传统测距的不方便性,根据激光相位式测距原理,提高了测距精度。利用正交小波包变换的盲均衡算法(WPTCMA),将硬件系统所获得的数据进行处理并最终显示出来。此防爆激光测距仪具有实用价值。According to the laser phase-ranging principle,which overcomes the inconvenience of underground traditional rangefinder and also improves the measurement accuracy.A wavelet packet transform based on CMA（WPTCMA） and its blind equalizer structure are proposed,eventually,the system of the hardware for processing the data was obtained and displayed.The explosion-proof laser rangefinder which has huge practical value.
