摘　　要：全面讨论了激光平面仪工作过程中激光的光学信号参数特性和光电传感器所接收到的光电信号的参数特性。为保证激光平面仪在大距离作业半径范围内能正常地工作，从理论上分析了在３００ｍ以内确保测平精度不超过１ｃｍ的可能性，为激光平面仪中接收装置的频谱响应和抗干扰性能参数的确定提供理论依据。The parametric performance of the optical signals and photo electric signals received by transducer was comprehensively discussed.In order to insure the laser plane system works ordinarily within the large operational radius, the possibility to ensure the measuring accuracy less than 1 cm within 300 m, has been analysed theoretically,and the principles of determining the laser plane system receiver frequency response and the immune performance parameter were developed.
