Abstract
The key technology that the attenuators of the continuous values are designed, manufactured and calibrated to calibrate the range of Laser Range Finder is discussed in this paper. The transmittance control technology of designing the continuous attenuator with a large caliber and 0.2dB-10dB attenuation continuously is sets forth, and the means of orthogonal polynomial surface fitting for continuous attenuation values are analysed, the utility calibrating results are also presented.
