Abstract:
     A method for raising measurement accuracy of visibility tester includes detecting attenuation voltage of optical antenna at emitting and receiving ends of visibility tester to certain detection light power separately first, then using the same light power to detect total attenuation voltage of visibility, finally obtaining atmospheric channel attenuation voltage by using said total attenuation voltage to deduct attenuation voltage at two said ends of optical antenna and using obtained atmospheric channel attenuation voltage to reflect height of visibility.
